New design low-cost transformers for wind farms


ACTOM Power Transformers lands sizeable order for new design low-cost transformers for wind farms

ACTOM Power Transformers has received an order for a large batch of transformers for wind turbine generators (WTG’s) for three new wind farms being established in the Northern Cape as part of the national renewable energy programme.

This follows the division’s earlier success in designing and producing similar transformers for one of the first wind farm projects in the programme, the Kouga Wind Farm near Oyster Bay in the Eastern Cape.

The latest order is for a total of 157 x 2700 kVA pad-mounted oil-natural air-natural (ONAN) transformers. It was placed by Midrand-based Consolidated Power Projects (CONCO), the electrical balance of plant contractor for the wind farms, Noupoort, Khobab and Loeriesfontein, comprising 35, 61 and 61 WTG’s respectively.

Independent power producer (IPP) Mainstream is the owner and developer of these projects.

The transformers contract was awarded in April 2015 and is scheduled for completion in mid-2016.

“In awarding the contract to ACTOM Power Transformers we took into account their success with the Kouga Wind Farm project, where the WTG transformers they supplied have proven to be efficient and reliable, so demonstrating their capability of meeting the special requirements applicable to wind farms,” commented Rein Dijkstra, CONCO’s Contracts Manager, Renewable Energy.

The new transformers incorporate a special feature that is new to South Africa but is well-proven abroad, especially in the US where it has been widely used for many years in wind farm and general distribution applications.

Gert Kriel, ACTOM Power Transformers’ Sales Manager, explained: “This involves making provision for accommodating the load-break switch together with current limiting fuses inside the transformer tank by mounting them under oil, in place of the usual external arrangement as applied to package transformers.

“This has the great advantage of significantly reducing the cost of manufacture and therefore the selling price.”

ACTOM (Pty) Ltd is the largest manufacturer, solution provider, repairer and distributor of electro-mechanical equipment in Africa, offering a winning and balanced combination of manufacturing, service, repairs, projects and distribution through its 40 distribution outlets throughout Southern Africa.

ACTOM is also a major local supplier of electrical equipment, services and balance of plant to the renewable energy projects.

It also holds numerous technology, distribution and value added reseller agreements with various partners, both locally and internationally.
