tribution lines. Generally a steel core is used with the aluminium to give the conductor me- chanical strength. This arrangement is termed Aluminium Conductor Steel Reinforced or ACSR. Conductors comprised entirely of alu- minium are known as All Aluminium Conduc- tors or AAC.These conductors are extensively used for busbars in outdoor substations where spans are short. All Aluminium Alloy Conduc- tors or AAAC consist of an alloying of alumin- ium to give a tensile strength in excess of that of AAC, allowing longer spans. These conduc- tors are recommended for coastal areas where severe corrosion is a problem. Aerial Bundle Conductors (ABC) Self-supporting system consists of four cores of hard-drawn stranded and compact- ed aluminum conductors of equal cross-sec- tion and insulated with carbon-loaded XLPE to ensure UV protection. All cores strained equally. Supporting core system consists of three phase cores of hard-drawn stranded compacted aluminium conductors insulated with carbon- loaded XLPE laid up around an aluminium-alloy supporting core insulated with carbon loaded XLPE to ensure UV pro- tection. Additional sub-conductors optional in both self-supporting and supporting-core systems. Airdac SNE and CNE Cable Circular stranded hard-drawn copper phase conductor, XLPE insulated with concentrically arranged identified neutral and bare earth con- ductors. Polyethylene sheathed 600/1000 V service connection cable. Nylon ripcord laid under sheath. Manufactured to SANS 1507 -6. Single Core XLPE PVC High conductivity annealed stranded circular copper conductors to SANS 1411-1. Insulated with XLPE to SANS 1411-4, and sheathed with general purpose PVC to SANS 1411-2. Bells and Mains Cable Plain copper conductors to SANS 1411-Part 1, Class 2. Two, three or four cores insulated with PVC, PVC bedded, steel wire armoured and sheathed with general purpose fire retardant PVC. O ver the last decade, CCG has been supplying the ever-growing global renewable energy market with cable glands and junction boxes. Some of the sig- nificant renewable projects supplied recently include: • 120 MW Shell Energy’s Gangarri Solar Farm, Australia. • 43 MW Ratch Australia’s Collinsville Solar Farm, Australia. • 143 MW Sun Metal Solar farm, Australia. • 116 MW Ross River Solar Farm, Australia. • 100 MW Chinchilla Solar Farm, Australia. • 100 MW KaXu Solar one CSP Project, Northern Cape. • 96 MW Jasper Solar Project, Northern Cape. CCG also recently supplied one of the larg- est offshore windfarm projects currently under construction. Situated 27 km off the coast of Scotland in the North Sea, the £3 billion Sea- green project, which is a joint venture between SSE and TOTAL Energy, will have 114 wind tur- bines with a combined rating of at 1075 MW and will supply enough renewable energy for the equivalent of a million Scottish homes. With the increasing worldwide move to re-

newable energy together and load shedding being experi- enced in South Africa, CCG took the decision to not only be a supplier to the renew- able energy sector but also to become a customer, user and producer. In August of 2021 CCG en- gaged the services of Wade Walker Solar to do a full as- sessment of its manufactur- ing plant in Kempton Park as to the suitability of installing a solar PV generation system.

HellermannTyton thrives on taking established design con- ventions for fixing parts and improving on them. So when the company received a request for a more versatile way to mount and clamp cables and hoses on construction ma- chinery, it rose to the challenge. The result is the Ratchet P-Clamp. It is the most user-friendly, versatile and robust P-Clamp for fastening and fixing cables, wires, pipes and hoses on the market. Especially for maintenance work, the Ratchet P-Clamp is the ideal solution: cables and wires can be replaced with ease, and without having to unscrew the product. All you need is a screwdriver to open the closure again. This means that the Ratchet P-clamp can be reused hundreds of times. Design makes the difference: how you benefit from our Ratchet P-Clamp HellermannTyton matched the Ratchet P-Clamp features to the following usability requirements: • Freedom of choice: separate pre- and final assembly stages. • Easy installation: close with one-hand. • Eliminate pinching: rifling centres the bundle automati- cally. • Re-open, re-use: easy release with a flathead screw- driver. • Reduce part inventory: four flexible sizes (6.2 mm-51 mm diameter). • Configure flexibly: multiple mounting plate dimensions available. • Maximise durability: toughened, UV-resistant PA66 and corrosion-free steel. • Optional extras: soft inserts and tension tab for repeti- tive quality. Advantages Advantage 1: You can pre-install the p-clamp before you close it With the Ratchet P-Clamp you can now determine the de- sired route for your cables, hoses or pipes before the cables, pipes or hoses have even been delivered!This two-stage operation also gives you the freedom to split the fastening and the fixing task in the time sense, or between different installers or contractors. You can even attach the clamps to the harness before it is installed. The Ratchet P-Clamp can easily by closed with one hand to the optimal diameter. The audible clicking as the ratchet assures the user that the clamp has closed securely. Advantage 2: You can re-open the clamp any time for maintenance In contrast to plastic omega snappers, push-in clips or two- piece fixing clamps, we designed the Ratchet P-Clamp so that it can be reopened simply without having to dismantle the bundle from the fixing points. This is a huge benefit for maintenance engineers, espe- cially when cable harnesses need to be adapted or modi- fied to fit new connection points. Simply insert a flathead screwdriver in the slot and lever out the ratchet closure. The plastic material is especially toughened so that you can re- open and re-use the clamp time and again. Advantage 3: Reduce the number of clamps and clips in your inventory The Ratchet P-Clamp is available in four sizes that are all adjustable. Part inventories can be significantly reduced and install- ers no longer need to carry a wide range of clips in different fixed diameters. With just four Ratchet P-Clamps and op- tional soft inserts you can do without dozens of aluminium clamps and metal or plastic p-clips. Where are Ratchet P-Clamps being used? Renewable energy sources, digital information systems and the electronics behind them continue to evolve in every as- pect of our lives. The complexity of the wiring schemes is increasing as a consequence. The Ratchet P-Clamp is being used by customers on photovoltaic installations and wind turbine towers, in trains, on ships and on all kinds of heavy duty vehicles like mobile cranes or agricultural machinery.

presses to run off grid for about six hours a day. Since commissioning the PV installation in mid-November, CCG has seen an immediate significant reduction in grid supplied electric- ity and it has been calculated that the cost of the installation will pay for itself within two and a half years. The other benefits are increased energy security of the manufacturing plant and an enhanced ISO 14001 Environmental Certi- fication rating by significantly reducing CCG’s carbon footprint.

By using figures for the existing energy load profile, historical electricity consumption data, measuring the area available for installing PV panels and using historical averages on the amount of available sun for the area, Wade Walker Solar proposed an installation of 1274 PV panels which would produce 574 KW dc converted to 500 KW ac. This would be enough for the whole factory consisting of 60 CNC machines, three plating plants, a reverse os- mosis water treatment plant and 30 moulding
