Duvha, Matla and Kriel
Eskom recently awarded a contract worth R20m to ACTOM Electrical Machines to manufacture and supply medium voltage motors to replace old motors at Duvha, Matla and Kriel power stations in Mpumalanga.
The utility identified a total of 29 motors operating in various applications at the power stations that were nearing the end of their lives and needed to be replaced.
The replacement motors range from 560 kW to 10 MW in power and their applications include driving of sluice pumps, ash pumps, AWR pumps, mills, blowers and PA fans. The contract was awarded at the end of April this year and is due for completion in early-2010.
“Because these are replacement machines we have to make sure the product we supply in all cases is interchangeable with the units on site,” commented Ernie Muller, commercial manager of the company’s Large Motors division.
“So before submitting our bid a site visit was arranged to take measurements on site to ensure that our motors would be both electrically and mechanically interchangeable with the old ones. Our motors, for example, have to fit onto the existing foundations and match the bolt-holes and cables that are there.
“In several instances where specs weren’t available for the existing motors we had to get them from the original supplier. In some rare cases we even had to establish the requirements independently, without any assistance from anyone.”
Muller said that in addition to the above vital factor and the competitiveness of ACTOM Electrical Machines’ bid, other factors that proved advantageous in winning the company the contract were its ability to meet the government’s ASGISA requirements regarding local content and skills development, among others, and its capability as a local manufacturer of offering readily available design expertise, spares supply and service backup.
