Department of Water Affairs
The Large Motors division of ACTOM Electrical Machines (formerly Alstom Electrical Machines), a member of South Africa’s largest electrical engineering group ACTOM, recently completed a complex contract for the Department of Water Affairs in which it produced made-to-fit medium voltage motors to replace existing motors operating at seven pump stations in Mpumalanga.
The motors, ranging between 1320 kW and 3455 kW, have been produced either to immediately replace an existing motor that has reached the end of its useful life or as a spare to replace the existing motor later. They include a dual-speed motor, which has been supplied for Rietfontein pump station, where a dual-speed motor is already in operation, and a motor with a variable-speed drive for Grootdraai pump station, which is an enhancement on the existing motor, which does not have variable speed operation at present.
The other pump stations covered by the contract – in all cases supplied with one replacement motor each – are Grootfontein, Zaaihoek, Jericho, Morgenstond and Kliphoek.
The contract was awarded in 2007 and was completed in September 2009, when the seventh and final replacement motor – for Jericho pump station – was delivered.
The division also recently completed two follow-up orders from the Department of Water Affairs for a further two replacement motors, the first being a second new motor for Morgenstond and the other for Camden pump station, also located in Mpumalanga.
Ernie Muller, Large Motors’ Commercial Manager, said the division has established a track record and developed a competency in executing replacement motors contracts that is well recognised in the market.
“We have gone out of our way to win challenging contracts like this in recent years as part of a drive to broaden our range of services,” he commented.
“The downside of these jobs, of course, is that they are much more complicated than your standard orders for motors for new projects. You have to design and make each individual motor to fit the foundation of its predecessor, right down to matching the bolt-holes and ensuring that it links up properly within the space constraints with the associated equipment on site. Time-consuming site visits and other research is involved and the design and manufacture of the motors are often quite tricky too.
“However, we find that in most cases the difficulties involved in these jobs is more than compensated for by the substantial size and monetary value of the contracts. Also they contribute very much towards strengthening our relationships with the customers concerned,” Muller concluded.
A spokesperson for the Department of Water Affairs said the department is satisfied with the level and quality of service ACTOM Electrical Machines has provided on the contract.
