ACTOM Electrical Machines wins motors order for Kusile’s desulphurisation plant

ACTOM Electrical Machines recently won a sizeable contract for the design, manufacture and supply of medium voltage motors for the wet limestone desulphurisation plant at Eskom’s new Kusile coal-fired power station currently under construction near Delmas, Mpumalanga.

The order, placed by Alstom S & E Africa (Pty) Ltd, the leader of the consortium responsible for the engineering and construction of the desulphurisation plant, comprises a total of 44 motors rated at 6,6 kV and between 300 and 1800 kW. The first deliveries are scheduled for June this year and the contract is due for completion in May 2014.
“This order comes after an extended commercial and technical evaluation process that began in late-2009,” said Sales Manager Brian Lindsay.
“The motors fulfil some unusually tough project specific requirements, including an expected operational life of 50 years, low full load sound levels of 82 db, resulting in the motors being constructed with integral sound attenuators, and a low bearing temperature rise of 35 degrees against a design ambient of 50 degrees, without the use of any external bearing cooling systems.”
The contract adds to a considerable volume of Eskom-related work in progress at ACTOM Electrical Machines, with many return-to-service contracts at various stages of completion within the works. The company has also recently received key orders from the Zimplats Ngezi Mine, Northam’s Booysendaal mine via DRA Group, the mining and mineral processing project management company, for large mill motors, some large pump motors for NamWater and various special purpose-built shredder motors destined for the USA market.
“It is encouraging to see good orders coming from the export and mining sectors again after a slow 2009 and early 2010,” Lindsay commented.
ACTOM (Pty) Ltd is the largest manufacturer and distributor of electrical equipment in South Africa, employing about 6 000 people and with an annual order intake in excess of R5bn. It is a black empowered company with 27operating units, 22 production facilities and 25 distribution centres throughout South Africa.

ACTOM holds exclusive distribution, technology and representation rights for Alstom Grid (formerly the Transmission business of Areva T&D) in Southern Africa and maintains management, technical and commercial links to Alstom Grid business units in Europe.

Following the acquisition by Schneider Electric of the global Distribution business of Areva T&D, the distribution, technology and representation agreements that existed between ACTOM and Areva will remain in place until such time as a new agreement has been concluded.

ACTOM formerly traded under the name Alstom South Africa and re-branded to ACTOM in September 2009.
