Mobile power for Kamoa-Kakula Mine, DRC The development of the world’s largest high-grade copper deposit – the Kamoa-Kakula Copper Project in the Democratic Republic of Congo (DRC) – now is running on power from the DRC’s national grid using a mobile substation recently commissioned by SouthAfrica’s Gauteng-based Zest Energy.The 120/11 kV mobile substation will serve the construction of the planned initial mine at Kamoa-Kakula, a project whose existing mineral resource has been independently veri- fied as Africa’s largest copper find. Kamoa-Kakula’s principal owners are Ivanhoe Mines, Zijin Mining and the government of the Democratic Republic of the Congo. “Due to the high cost of running on diesel generators, themine developers decided to purchase a mobile substation to interface with the network of the DRC power utility SNEL to provide power during the construction phase of the project,” Alastair Gerrard, managing director at Zest Energy, says. Zest Energy – part of the Zest WEG Group – undertook the design, manufacture, supply, testing, delivery, installation and commissioning of the complete mobile substation, including the trailer, transformer and related electrical equipment. It also provided a protection system, earthing, site work (with full commissioning and testing) and site training.

ATEX and IECEx certified, the high powered LED light source gives light output up to 189 lumens. The bespoke optics deliver a high intensity narrow beam with a lower output wide angle fringe light, making the new M-85 Midi Torch ideal for inspection and maintenance work in conditions of darkness or reduced visibility. The new Midi torch is safe for use in Zones 0 (gas groups IIC/ T3/4) and 20 (dust group IIIB / T200°C), has a gas ambient temperature range from -40°C, to +40°C and is approved for Group I M1 mining areas.This single-handed push button switch has a rubberised switch cover and raised surface to allow easy operation even with gloved hands. The strong, durable torch body enclosure has excellent chemical resistant properties and a proven impact resistance, even at sub zero temperatures.The rubber armoured lens ring gives enhanced grip and shock protection with a shatterproof polycarbonate lens providing excellent resistance to impact damage.

Increasing local assembly capability Paying a visit to the South African head office in Johannesburg recently, SEW-EURODRIVE GmbH President and Managing Director, Jürgen Blickle, commented that, while the mining industry was still in a slump, “We are still very strong in mining.” Blickle revealed that the OEMplanned to ramp up its local assembly op- erations, with an expanded assembly facility on the cards. Another key focus for future growth was boosting the aftermarket sector, which has seen SEW-EURODRIVE South Africa establish a new Field Service Department and Repair Cen- tre. “We want to increase the service business, including servicing brands other than our own. This is an international trend, whereby we find customers ap- proaching us for this particular ser- vice,” Blickle stressed. However, Blickle added that the main focus is still offering complete replacement units wherever possible. “As so many of our products are largely identical and interchangeable, we will simply offer a replacement unit as opposed to repairing an old one.” In South Africa, the Johannes- burg assembly facility has invested significantly in installing the latest As- sembly Islands to streamline produc- tion and reduce waste, an upgrade that will be carried through to the local branches in Nelspruit, Durban, Port Elizabeth, and CapeTown.
