NEW HellermannTyton MANAGEMENT TEAM ANNOUNCED

HellermannTyton South Africa's new management team: Gerhard van Rooyen and Claude Middleton.

W ith the impending retirement of outgoing HellermannTyton South Africa Managing Director, Rod Dewing, changes have been made to ensure that the company continues to prosper. Claude Middle- ton has been announced as the new MD – previously Director: Sales and Marketing – and Gerhard van Rooyen – previously Director: Finance – is the new Director: Finance and Operations. “Although there are changes at the top, we are still HellermannTy- ton, and will continue giving customers the same quality product and the same service levels they have come to expect,” says Middleton. With a combined 17 years at the company, Middleton and van Rooy- en’s appointments are in keeping with the global HellermannTyton ethos of promoting from within. This practice reinforces continuity by promoting staff who understand how HellermannTyton operates and know the business methods and what the HellermannTyton brand stands for. “Gerhard and I have been here long enough to become entrenched in the HellermannTyton brand and we will ensure that we build on the traditions of the company,” he says. Middleton will still be responsible for the sales and marketing func- tion, along with product and quality management; van Rooyen mean- while will, along with finance, IT and administration, oversee the op- erations side of the business, including manufacturing, warehousing, distribution, supply chain and human resources. Despite losing a man of Dewing’s vast experience, the new man- agement duo believes they are up to the task, and have learnt many lessons from the outgoing MD. “The business is 52 years old and Rod has been involved for half of that time, so he has been instrumental in the growth of the business along with setting up the world-class production facility we have here,” says van Rooyen. “From a culture aspect, he had a people-orientated way of leading. He always put peo- ple first and that legacy will remain with the business for quite some time.” Middleton agrees, “Rod had an open door policy, which is rare in businesses of this size, and would not make a decision without first consulting people, yet once a decision was made, Rod was very firm and committed. He oversaw the company’s move from smaller begin- nings in Johannesburg to Linbro Park where we have since doubled the facility, and he has been instrumental in growing the company to the point where we now manufacture and supply products into other parts of the world.” When asked about Dewing’s plans for the future, Middleton laughs

and responds, “Lowering his golf handicap! I think initially he will take a bit of a rest; running an operation like this, and considering the diversity of busi- ness – from supplying insulation tape which goes into the electrical industry to automotive mould tools which supply products for the S-Class Mercedes Benz – there are well over 5 000 product lines, so the job does take a lot of effort and focus.”

CELEBRATING 90 YEARS IN SOUTH AFRICA BMG – which acquired FPT Distribution SA (Fenner Power Transmission) over 20 years ago – celebrates Fenner’s 90 th year of business in South Africa this year. “The BMG team is proud to be the exclusive distributors of highly acclaimed Fenner products, which have been manufactured in South Africa for longer than any other power transmission brand,” says Carlo Beukes, business unit manager, Power Transmission, BMG. “Fenner, which was established in England in 1861, re- mains the premium brand in power transmission, that generations of professional engineers have depended on and trusted. “Fenner power transmission products are synon- ymous with quality and reliability globally and have set the benchmark high for dependable compo- nents for high efficiency, low maintenance require- ments and extended service life – even in the most arduous operating conditions. “An important factor for BMG in marketing Fen- ner products is the ‘Fenner Quality Assurance Ini- tiative’, which is a worldwide commitment to quality. Customers have the assurance, wherever they are located, that the quality of Fenner products always meets exacting, agreed and internationally recog- nised industry standards. “Because standardisation and spares-holding costs are a high priority for most production op- erations, Fenner applies a policy of low-frequency product changes throughout its portfolio, with de- sign improvements implemented only where these will offer significant customer benefits. BMG’s Fen- ner range – which consists of transmission and drive chains, vee and wedge belts, tyre and grid couplings, timing belts, sprockets and pulleys, and shaft mounted speed reducers – enables BMG to work with all sectors of industry. The company also services the industrial and mining replacement and re-sale markets and is a supplier to original equipment manufacturers. A strategic decision was made by BMG earlier this year to expand the portfolio, with the addition of Fenner conveyor belting products. Through a long- term agreement with Fenner Conveyor Belting, BMG is now the exclusive distributor of Fenner con- veyor belting products locally and in sub-Saharan Africa. Fenner conveyor belting products, which in- clude steel cord and solid woven conveyor belting, are manufactured at the Isando plant, according to stringent international quality standards. BMG – with a technically competent team and a well- established network of over 130 branches – is well-positioned to develop sales opportunities and continue to provide support for the entire Fenner portfolio.

PERSONALITY OF THE MONTH – FRANCESCO ABBATE

THE SECRETS BEHIND A 30 YEAR CAREER IN THE SOUTH AFRICAN LIGHTING INDUSTRY

Sparks: When and where did you start your career? FA: My career started in South Africa when I decided to import light fittings from Italy in 1986. Then in 1989, when the South African market was facing an uncertain future, I decided to open Spazio Lighting and the rest, as they say, is history. Sparks: What are the greatest changes you have seen over the years? FA: Throughout the years, I have seen several technology changes, however, the few that stand out for me would be the fluorescent technology, the low voltage technology and today the LED technology. Sparks: What major projects have you worked on and what is your greatest accomplishment? FA: Some of the projects that Spazio has contributed to that really stand out for me include the Cape Town International Airport, Green Point Stadium in Cape Town, Gateway Shopping Centre in Umhlanga, Pick n Pay stores throughout the country, the Houghton Mosque as well as many hotels in South Africa and abroad, including 15 on Orange in Cape Town. I feel that my greatest accomplishment is the fact that after 30 years, Spazio is still one of the leading lighting companies in South Africa and that most of my staff have worked with me for all these years towards this achievement. Sparks: Who has been your inspiration or have you had a mentor who has influenced your career? FA: My father was a great teacher and I have learned a lot from him, however, I take mentorship on a daily basis, looking at how other businesses are run and how the world’s leading brands operate. Reading about and observing other businesses’ strategies is what allows me to improve my company. Sparks: What, to your mind, is one of the biggest challenges facing the industry at this time? FA: The misconception of LED in general also being fuelled by the poor quality of some of the products on the market is a big challenge. Customers and consumers still believe LEDs to be an endless source of illumination and do not take into account that different LED sources will have variations in quality. Sparks: What do you enjoy most about your job? FA: What I enjoy most about my job is the challenge to continuously stay up to date with the latest trends and technologies and introduce products into the South African market that are not only

up to standard, but are also economically viable for the South African market. This continuous challenge and the satisfaction I receive from achieving these goals is what I enjoy and what motivates me on a daily basis. Sparks: How do you motivate your staff? FA: I view fairness and understanding each person as a key factor of my management skills. I think that working together and not working for me is what my staff enjoys.

FRANCESCO ABBATE, Managing Director of Spazio Lighting is a man who does not rest on his laurels. Despite founding and running one of the leading lighting companies in South Africa for 30 years, one of the things he enjoys most about his job is continuously staying up to date with the latest trends and technologies, along with observing other businesses’ strategies to help him to improve the company. Sparks: Where were you educated? FA: I completed a Diploma in Science from Liceo Scientifica Rodolfi in Milan, Italy. Sparks: How long have you been involved in the lighting industry? FA: I was trained by my father, Mario Abbate, in the lighting industry. From the age of 10 I used to visit the Milano Lighting Exhibition with my father, if only for a few hours. When I was 14, I used to earn pocket money by assembling electrical track adaptors for my father. During our summer holidays, at the age of 16, I used to work full-time at my father’s factory, in the warehouse. This experience has been extremely valuable because it has allowed me, from a very young age, to have a clear picture of the work that is required on the operations side of the business that I currently run.

TALKING ELECTRICITY WITH ANDREW LUKE DAPSHIS

AUTOMATIC CHANGE OVER PANELS AND OUTDATED ELECTRICAL SYSTEMS D ue to the current load shedding and Es- kom’s endless problems, a lot of people have turned to generators and automatic

rotation, as many of the older municipal supplies are still anti clockwise and most, if not all, new generators are clockwise. This will of course cause a change in motor direction if you don’t swop two phases around on your generator’s isolator. There are many different panels and backup solutions out there; ensure you choose one that can supply your current load requirements at its peak and, if necessary, ensure a dummy load is present when the current drawn is less than 50% of the generator’s kW rating. There is much load shedding and electrical challenges ahead in our great country, so ensure you do your research before spending thousands and gathering further frustration when it doesn’t function correctly.

the automatic change over panel controller, and must now explain in easy-to-understand terms why it is constantly switching on the generator. Systems like these can, of course, be bypassed, but then you are eliminating a safety device set to protect your system and, in many cases, once you have done that there is a chance you could void your warranty. Always ensure, no matter where you are, that if you are going to spend a large amount of capital on a standby solution that you organise a data logging electrician to do a test on your system to ensure you know, and are advised according, to your load and the municipal supply. Another element to always check is phase

standby option and to do this seemingly she buys a automatic change over panel. Now prime time comes and Mary hears her generator starting up and her fluorescent lights flicker, but across the road, Larry’s Laundromat, which doesn’t have a generator, is still running off grid power. Mary thinks that she has bought a dud setup that has gone bonkers, but seven minutes later she hears her generator stop, the fluorescent’s flicker and she is back on municipal supply. This happens a few times and Mary gets upset and calls the generator company, claiming the system is faulty and is costing her a lot of diesel. A technician is despatched and is greeted with a host of mains voltage drop/overload alarms on

change over panels to handle a quick and seem- ingly easy transition from the grid to backup solu- tions. Many of the latest automatic change over panels have numerous measuring devices working through a controller that constantly monitors your mains supply along with your generator’s load in order to best protect your electrical infrastructure. It works through a dual set of interlocked contactors to change from municipal to generator supply. So, in many of the older areas where the municipal electricals systems haven’t been upgraded for 20+ years, at various times to handle the massive demand on these systems and the volt drop that inevitably happens, the municipal supply increases their voltage in order to handle the prime time requirements. So the three phase voltage picks up from 380-402 V to 450 V and the controller on the automatic change over panel picks up this increase in voltage and decides it is best to start and run the generator and disconnect from the mains in order to best protect whatever machinery is being run. Many times this transition happens within a split second, depending of course on what which is bought. Many of the newer automatic change over panels can also be fitted with cloud devices, working through a 3G sim card to allow real time access to your system via your cell phone and send you messages every time your generators starts or has a fault. But now we sit with an issue in many cases with older systems utilising new technology; people have no indication that anything is wrong with their systems as no one sits motoring their drawn voltage or current on a by minute basis. So Mary Mango buys a rundown building in the old part of town and turns it into a success, so she opts for a generator due to constant load shedding. Knowing nothing about electricity, the salesman sells her a 20 kW to supply her shop with a great Sparks: If you could ‘do it all again’, would you change anything? If so, what would that be? FA: I would probably look for a partner with a lot of money and not build up the business from scratch. CAREER IN THE SOUTH AFRICAN LIGHTING INDUSTRY Sparks: Would you advise a person leaving school to enter the lighting industry? And why? FA: Yes, I would advise someone to enter the lighting industry because it allows a person with a strong electrical or technical knowledge, together with a good sense of aesthetic and design, to apply this technical knowledge to design. Sparks:What is your advice toelectrical contractors, electrical engineers or lighting designers? FA: • Don’t go for price first. • Analyse your customer’s requirements and ex- pectations. • Spend a little extra time to do your installation 100% accurately.

PLUGGING INTO NEW SA SAFETY STANDARDS

F or those who are still in the dark, the South African Bureau of Standards (SABS) recently announced new plug standards that are now mandatory, and which you need to know about – es- pecially if you have home renovations or building on the horizon. Orlando Luis, CEO of Brights Hardware, explains that South Africa has adopted new plug standards – which means we will be phasing out the common fa- miliar triangular electrical plug and socket currently used, and changing to the new ‘ZA Plug’. “The new plug has the same hexagonal profile as the Europlug seen on cell phone chargers and in- cludes an earth pin. It is substantially more compact

the electrical sockets in your home if you are reno- vating or building onto an existing structure. Further- more, there are no strict deadlines for the switchover from current to new plug standards – so it is ‘busi- ness as usual’ unless you are building a brand new home. “Anyone who has questions or needs advice about electrical installations or the new ZA Plug standards, and what they need to do, can visit a local Brights store in the Western Cape and chat to one of our technical sales specialist,” says Luis. “Brights also stocks current electrical plug points and the new ZA Plug sockets.” Cell phone chargers and devices using standard

than South Africa’s three-prong plug standard, and has much thinner pins,” says Luis. “However, despite the fact that it is now required to integrate sockets that comply with the ZA Plug standard in new buildings, the old standard remains legal and the wiring code amendment does not af- fect existing buildings. This means is that new build- ings must conform to the new electrical plug socket standards.” Luis says there is some confusion as to what con- stitutes a ‘new installation’, explaining that this must be interpreted as a totally new building, and that renovations and maintenance would be excluded. The good news is that it is not necessary to switch

DB MAINTENANCE: THE SILENT DESTROYER O n route to delivering DB boards, vital components and connections might vibrate loose due to the vibration of the truck and road conditions. Although care should be taken at the factory to ensure that all connec- tions are tightened correctly and bus bar con- nections torqued at the required setting, it may be necessary to check these connections before commission of the board. George Switchboards suggest that due to the nature of our industry and components we work with, maintenance might be required every six months, specifically to power factor units and circuits that intermittently get energized i.e. out- side lighting circuit on a contactor. Have you ever thought that due to the prolonged period of expo- sure to light vibration at 50 Hz of the cables under load, thermal conditions and the expansion coeffi- cient of metals the connections might loosen and need adjustment? It is healthy for the board to be kept neat and as dust free as possible as well. The internal heat generation of circuits pose a fire hazard when combined with dust which can also damage and shorten the lifespan of components. These factors, however minute, are a problem we face in the electrical industry which makes maintenance of extreme importance to ensure longevity of any components and installations. George Switchboard Manufacturers has been in existence since 1958. The company provide vari- ous products to the energy distribution network, and more specifically, the electrical distribution network across the African continent. Europlugs will fit in the wall sockets. Annoying ‘double-adapters’ will be a thing of the past – no more wiggling a two-prong plug to get it to work, or struggling to get a plug to go into low- quality adapters. No more multi-plugs that are not fully utilised – many electronic devices come to South Africa with Europlugs attached, resulting in adapters nev- er seeing an ‘old’ three-pronged plug any more. New wall sockets can fit much more than two plugs, like the old wall sockets. You can fit at least two ZA Plugs into the space of one of the triangu- lar sockets. The new ZA Plugs are safer than our current sockets and children’s small fingers and small ob- jects will no longer fit into wall sockets. Plus, the recessed sockets on the ZA Plug mean that small fingers can no longer wrap over the edge of the plastic plug and risk touching a live prong when pulling a plug out of the socket. The newplug standardsmean that plugs and ca- bleswill take up less spacewhen being transported. Enquiries: www.brights.co.za

COMPACT LOVATO ADXL SOFT STARTERS FOR THREE-PHASE MOTORS S oft starters limit the inrush current, improving overall stability of the power supply, and reduc- ing transient voltage drops, which may affect languages. Icons indicate default application set-up in use, while graphic bars indicate the motor and in- ternal thyristor temperatures, and an alphanumeric display shows texts and measurements as well as the current status of the starter. fire-fighting pumps, conveyer belts, fans, mixers, and general purpose. Selecting the required application automatically updates the parameter programming to the requested application.

WARNING LABELS FOR TERMINAL BLOCKS WITH PUSH-IN CONNECTION The ADXL series is equipped with built-in elec- tronic overload protection, protecting the motor from overheating. No additional overload device is required, saving space and installation time. A backlit LCD icon language-neutral display is incorporated on the fascia for quick and easy configuration and visualisation of all measurements and status pa- rameters. Alarms and text can be displayed in any of six other loads in a network. They are Ideal for applications demanding high-performance in terms of control and protection during motor start-up and operation. Soft starters can avoid pressure surges and pre- vent water hammering (normally a big problem) in pump applications. Conveyor belt systems can be started smoothly, avoiding jerk and stress on drive components. Fans or other systems with belt drives can be started slowly, avoiding belt slipping. The new ADXL series from Lovato, distributed by ElectroMechanica (EM), comprises modern, state- of-the-art, compact soft starters for three-phase motors from 7.5 kW to 160 kW, in four frame sizes, EM Product Manager Jaap Grobler explains. It allows for control of starting, stopping, monitor- ing, and protection, with integrated functionality for an extremely efficient starting solution. A bypass facility is provided on all sizes, which operates when the start-up function has completed, thus reducing power losses and saving energy. A wide operational voltage range of 208 V ac to 600 V ac, a compact design, and advanced func- tionality make the ADXL series a highly efficient solution for most applications in all industries. Two- phase control during motor starting and stopping, combined with torque control during operation, pro- vides optimised ramping characteristics. This ensures smooth start and stop functionality for all applications, significantly increasing lifespan of connected motors and power transmission de- vices. Hence the ADXL series is an excellent choice for pumping applications where water hammering is normally a major problem. Kick-start functional- ity delivers high torque only during the initial starting period, permitting motors to be started when initial torque is insufficient to overcome friction.

Programming can be done via the front four but- ton controls, together with the Icon display, or via a front-mounted optical port that can be configured to connect to a computer via USB or WiFi using optional accessories, or simply via NFC (Near Field Communication), using compatible smartphone or tablets, even with the starter turned off. All ADXL series soft starters are equipped to re- ceive a dedicated RS485 Modbus communication card, permitting constant monitoring of all starter measurements, or to connect to an optional remote

Input and output functions are pre-configured to the most common settings, but can be easily over- ridden to adapt the soft starter to specific application needs. The ADXL series incorporate two counters dedicated to count the number of start-ups and mo- tor operating hours to set possible thresholds to ac- tivate an alarm for potential maintenance purposes. Set-up is a breeze, as the ADXL soft starters are supplied pre-configured out-of-the-box for most common applications such as centrifugal pumps,

Catering for both the slimline earthed plugtops as well as the non-earthed euro 2-pin plugtops, these two slimline sockets cater for multiple applications. Another benefit for the end user is that the three outlets limits the need for adaptors. The 164-1 socket is accompanied by two slimline sockets to meet the new building regulations as well as to allow for user versatility.

CRABTREE ELECTRICAL has recently introduced a new com- bination socket to the market. Locally designed and manufac- tured, the socket boasts a variety of benefits for installers as well as end users. Featuring a triangular layout box terminal design, the 16 A 250 V rated monoblock socket allows for easy, hassle free wiring and installation. The large mov- ing box terminal size allows for easy wiring and wire looping for thick wires with its exceptional clamping ability. Wire entries are all from one angle and screws from another angle to ensure that the wiring process is easy and convenient. Once installed,

“In his words, he owes his family a lot of time,” notes van Rooyen, pointing out that after 26-odd years with a business you do not simply cut ties. “He will still be available for a chat, and despite the ‘changing of the guard’ becoming official on January 1st of this year, Rod is here until the end of March. When he walks away, having invested so much time in the company, he will want to know he has left a stable company in the right hands.” The road ahead for HellermannTyton The new management duo want to ensure that the company’s brand and products remain number one in the chosen markets in Sub-Saharan Africa, and also want to grow the product offering into renewable energy. “We see that as a key growth area, along with the engineering division we acquired three years ago,” says Middleton. Focus will be placed on the plastic injec- tion tool design and manufacturing division of the business where custom moulding has been identified as a possible growth area. “We all know that the economy is not where it should be, so if there’s no growth you have to go and find it and diversification is key,” states van Rooyen. With this in mind, being solutions-based, as opposed to product-based is imperative. “We want to gear the business towards providing solutions, whereby we help with the design of product, as well as the manufacture; providing a total solution for clients,” he says. Middleton notes that with times being tougher, HellermannTyton is aiming to provide a better, faster and smarter solution. “As we are part of the global HellermannTyton group, we have the strength of the group behind us, which gives us access to global design teams and software, so although we can provide a local solution, it is with the backing of a large global team.” Challenges to overcome “Our biggest challenge at the moment is Eskom and, apart from other obvi- ous risks, we are a player in the electrical industry. If your only electricity sup- plier fails, that is a problem,” says van Rooyen. “You can try to mitigate it as far as possible,” continues Middleton, “but if there is no electricity, the electrical market will not grow. As we have mentioned, we are diversifying, however, our roots are still strongly based in the classic electrical market in South Africa – it’s our core income stream. Eskom’s failures and load shedding have an immediate and very direct impact on the company due to the fact that we are a local manufacturer.” The pair still feels positive about the future, however. “Despite Eskom and some of the political challenges the country faces, the positive is that with a small amount of effort we have a lot of turnaround potential in South Africa,” explains Middleton. “We are rich in natural resources, we have good work eth- ics, we have skilled people and we have quality manufacturing in the country. It is not as if we have to build all that – it exists. With some key focuses, I think the potential for a quick turnaround is there,” Van Rooyen agrees; “The signs are that things are about to change.” Despite the changes internally at HellermannTyton, it is clear that the new management team in charge of the company is ready to drive the company forward by leading by example. “I have always prided myself on being an enabler and being inclusive, and that style will continue in my management,” says Middleton. “Although management leads by example, you cannot do everything and need to offer an environment where people can flourish. With Gerhard and me at the helm, it is still the same HellermannTyton people have come to trust.” NEWHELLERMANNTYTON MANAGEMENT TEAM ANNOUNCED CONTINUED FROM PAGE 1

COMPACT CONTACTOR SOLUTIONS

E ngineered to provide a compact contactor solution, the WEG CWB range of devices offers a width space saving of up to 18%. Developed in two frame sizes, the contactors meet a range of industrial and domestic application requirements. The first contactor in the range, covering up to 38 A, has a width of only 45 mm while the second contactor, ranging from 40 to 80 A, has a width of 54 mm. Two mounting options, standard DIN rail or oblong mounting holes makes interchangeability easy. Significantly, the space saving allows the use six contactors where previously only five could be used. Another innovative engineering feature is the use of WEG’s Zero-Width mechanical interlocking system. Traditionally contactors use a mechanical interlock device which is external to the contactor. The Zero-Width system facilitates quick and easy mechanical interlocking between contactors, without the need for tools. In addition, this feature allows the user to build a reversing starter up to 38 A with a total width of only 90 mm. IP66 SEALED ENCLOSURES FOR INDUSTRIAL APPLICATIONS O ptimised for use in harsh industrial en- vironments, the 1554 flat lid and 1555 styled lid ranges of ABS and UV stabilised polycarbonate enclosures from Hammond Manu- facturing provide IP66 sealing and good mechani- cal protection. The light grey RAL 7035 enclosures are designed to house printed circuit boards or DIN rail mounted components. IP66 sealing is achieved through a one piece silicone gasket in a tongue and groove seal. 23 sizes from 66 x 66 x 41 mm to 239 x 160 x 119 mm are available with flat and styled self-coloured, clear and translucent lids. Flanged lids for 10 sizes, from 119 x 66 x 42 mm to 180 x 119 x 62 mm, provide increased security by preventing ac- cess to the interior without removing the enclosure from the surface to which it is attached. The styled lids include a recess suitable for mount- ing a membrane keyboard and are also fitted with PCB mounting bosses. Bases are fitted with internal DIN rail mounting tabs in all but two sizes and stand- offs for mounting PCBs or optional internal panels are provided in all versions. To avoid any possible corrosion problems the base inserts and self-captivating lid screws are both stainless steel, located outside the gasket; additional holes in the base, again outside the gasket seal are provided to allow the enclosure to be wall or shelf mounted. An optional foot kit is also available. Op- tional steel panels suitable for mounting heavy com- ponents can be fitted to the integral mounting points in the base; the bases also feature moulded slots to enable 1.6 mm thick PCBs to be mounted vertically into the enclosure. Available in South Africa through Mouser Electronics.

Built-in front auxiliary contacts not only enhance the space saving benefit, but also eliminate the need to purchase additional auxiliary contacts. This feature also offers greater flexibility as it facilitates optimisation of the internal space in electrical panels. In another innovation, the contactors have been engineered with integral surge suppressor blocks without increasing the physical size of the devices. This limits undesired interference which could be caused during the opening of the contactor coils and allows for the front mount surge suppressor to be easily removed without the use of special tools. Energy saving is achieved through the low consumption of the coils, which allows direct switching from PLCs without the need for interface

network, the WEG CWB range of contactors affords customers a high level of flexibility.
