South Africa: South African transformer manufacturer Trafo Power Solutions has received order for additional six dry-type transformers to be installed at a mobile process plant at a Sierra Leone mine.

Four of its dry-type transformers were installed at the plant last year. The second contract is a repeat of the initial order and comprises two 800 kVA units, one 1,600 kVA unit and one 2,000 kVA unit as well as a further two transformers - 1,600 kVA and 800 kVA - which will replace two existing oil-filled transformers, reports International Mining.

Trafo Power Solutions Managing Director, David Claassen, said: "The mine required a solution that would withstand the demanding conditions of a mobile process plant needing to be moved frequently over rugged mining terrain - as often as once a month. They could not risk using a conventional oil-cooled transformer as they needed to avoid any risk of fire or oil leaks. They also needed a product that would require little to no maintenance."

The transformers are installed in a six-meter long E-house on the mobile process plant, which is moved around the site on skids as required by the mining plan.
