Trafo Power Solutions has customised two dry-type transformers for a coal mine in South Africa’s Limpopo province, allowing the units to be fitted into existing enclosures while meeting the customer’s demanding duty requirements.
“While we would normally supply the transformer together with its enclosure, we are also able to design the solution according to the dimensions available on site,” said David Claassen, Managing Director of Trafo Power Solutions.
This required one of the transformers – a specialised 3900 kVA unit – to be copper-wound to achieve a smaller footprint suitable to the space constraints without compromising the technical performance. With 11 kV capacity on the primary windings, this transformer included four separate secondary windings – for 1810 V, 1515 V, 1360 V and 1210 V output respectively.
