A new 435 m² machine shop workshop and transformer department at Marthinusen & Coutts’ facility in Kitwe, Zambia, will further improve the quality and turnaround time of its services in the region.

According to Marthinusen & Coutts Zambia General Manager Eugene Lottering, the commissioning of the machine shop workshop in January this year created significant space in the 1700 m² main workshop, allowing for the investment in a transformer department.

The new 435 m² machine shop workshop at Marthinusen & Coutts Kitwe facility will further improve turnaround time.

“We now have a dedicated factory for machining work-pieces for the main shop,” says Lottering. “The Marthinusen & Coutts head office in Johannesburg plays a key role in our operations, sending its machine shop foreman to provide training. This enables us to upgrade local Zambian machining skills on a continual basis.”

The division’s machine shop facility boasts five machining lathes, two milling machines and a submerged arc welding machine. It also has a 50-tonne horizontal press and rotor binding machine. All equipment operates under two 6.3-tonne jib cranes.

“Our transformer department has allowed us to enter the market in transformer repairs. The facility is equipped with a 20-tonne overhead crane to lift larger transformers,” he says.

The facility is also equipped with a new coil machine, ratio tester, an oil purification machine and a dedicated oven.

Marthinusen & Coutts, a division of ACTOM, has already successfully overhauled transformers for a number of opencast mines. Projects have included a 10 MVA unit, two 5 MVA units and a 3 MVA unit. Working in collaboration with M&C Johannesburg has ensured quality standards are maintained while local transformer repair skills are also being developed.

“We have established a Level 3 maintenance site services team to provide on-site electro-mechanical assistance to customers, including on-site repairs, maintenance and testing,” Lottering adds.

Significant previous investments in the division’s Kitwe workshop have included a 12-tonne balancing machine, a vacuum pressure impregnation (VPI) plant, burn-off and curing ovens, and a fan test column. There is also an ac and dc test facility equipped with power analyser, surge comparison tester, core flux tester and high voltage pressure tester.

“Our ongoing investment in the region enables us to provide customers with a one-stop electro-mechanical repair facility for alternators, generators, motors and transformers, as well as mechanical equipment,” Lottering says. “This means shorter lead times and less transportation risk, while benefitting the Zambian economy.”
