Local transformers for Kusile power station

in South Africa
Johannesburg, South Africa — ESI-AFRICA.COM — 17 February 2011 – Eskom’s new Kusile power station “’ currently under construction near Delmas in Mpumalanga “’ is to be fitted with locally designed and manufactured unit transformers produced by ACTOM Power Transformers.

ACTOM 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 R5 billion. It is a black empowered company with 27operating units, 22 production facilities and 25 distribution centres throughout South Africa.

In a statement released here, the company said that its capability to manufacture unit transformers flowed directly from substantial extensions it had undertaken in recent years at its Wadeville, Germiston, plant to both increase its total production capacity and extend the upper power limit of its product to 160 MVA at 132 kV.

The R215 million, five-year, turnkey contract Eskom has awarded to ACTOM Power Systems “’ which is the ACTOM Group’s electrical infrastructure project management and construction company “’ incorporates design, production and supply of 13 unit transformers – two per generator unit, plus one spare. They are specified with dual secondary windings and rated at 110/55/55 MVA and 22/15,75/15,75 kV.

The unit transformers – the first to be produced by the company – comprise the largest portion of the contract, which also involves the provision of the associated earthing system and secondary protection that includes on-line gas analysis, a transformer explosion prevention system and an emulsifying deluge system.

ACTOM Power Systems is due to commence installation of equipment for Kusile’s first generator unit in April 2012 and will commence work on the others at eight-monthly intervals thereafter. The contract is scheduled for completion at the end of 2015.
“ACTOM Power Transformers’ capability to design and manufacture the unit transformers locally was the single most important factor behind Eskom’s decision to award us the contract in the face of stiff competition from other contenders – most of them foreign companies,” commented, ACTOM Power Systems General Manager John McClure.

Another key factor that favoured the selection of the local company over foreign manufacturers was that it provided Eskom with additional scope for setting local content requirements and applying the Accelerated and Shared Growth Initiative for South Africa (ASGI-SA) provisions that Eskom and other parastatal bodies and public sector organisations subscribe to as part of their conditions of contract.
