Power Transformers: Divisional News
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.
Transformers for City’s Sebenza intake substation

eThekwini Electricity R107m Contract
eThekwini Electricity has awarded a R107-million contract to ACTOM Power Transformers to produce four 315 MVA 275 kV/132 kV autotransformers for Klaarwater substation, one of the main intake substations for Durban.
It is the first contact the company has won for power transformers of these power and voltage ratings. The largest power transformers it is currently equipped to manufacture are 160 MVA 161 kV units.
Bloemfontein’s electricity crisis
On May 27, 2011, Bloemfontein suffered a major blackout due to a power failure in one of its primary electricity distribution centres, the 132 kV/33 kV/11 kV Bayswater, which provides approximately a third of the city’s electricity supply.
The power failure also triggered a water supply crisis, as Bayswater is the power source for the city’s main water supply. “While Bayswater was down Bloemfontein was solely reliant on its own internal supply from Maselspoort Water Treatment Works, which provides 40% of the potable water,” said Leon Kritzinger, Executive Manager, Engineering, of Centlec, Bloemfontein’s electricity supply company.
MeerKAT Radio Telescope
ACTOM Power Transformers has been contracted to produce two 5 MVA power transformers for installation in the 66 kV/33 kV Karoo substation which will supply power to the MeerKAT radio telescope – a 64-dish array radio telescope to be built in the Karoo.
The contract, awarded by Square Kilometre Array (SKA) South Africa to ACTOM Power Transformers in March this year, is due for completion in February 2012. It encompasses manufacture, supply, installation and acceptance testing of the two 5 MVA transformers.
ACTOM Power Transformers “now ready”
After its successful completion of the design, manufacture and supply of four customised 60 MVA 12/132 kV power transformers as replacements for the original units in the City of Cape Town’s 180 MW Steenbras pumped-storage power station near Gordon’s Bay, ACTOM Power Transformers is well-placed to provide power transformers for power generation of all kinds.
Kusile Unit Transfromers
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 group company ACTOM Power Transformers.
First High-Rated AutoTransformer
Since completing a major upgrade and extension of its Wadeville, Germiston, plant three years ago, ACTOM Power Transformers has designed, manufactured and supplied its first large Eskom spec autotransformer – a 120 MVA unit – which is to be installed in George Municipality’s new 132 kV/66 kV/11 kV Schaapkop main intake substation currently under construction.
