It has been five years since Trafo Power Solutions supplied Alphamin’s Bisie tin mine in the Democratic Republic of Congo with two dry-type transformers; they have performed so well that another three of these modular substations equipped with dry-type transformers will soon be on their way, to keep up with the mine’s expansion.
“This latest order is testament to the operational performance of our dry-type transformers at Bisie mine over the past five years,” says David Claassen, Managing Director of Trafo Power Solutions. “There were numerous challenges that our design had to accommodate, not least of which is a very arduous section of road in the journey to the mine.”
The mine’s location in the Walikale Territory of DRC is remote, being about 180 km north west of Goma, and more than 30 km from the national route linking Walikale with Kisangani. Like the initial order, the three 3000 kVA, 400 V/11 kV substations will be supplied in standard six metre containers to facilitate transportation. However, specialised steel bracing is required – to withstand the challenging road conditions, especially over the last part the journey.

“These conditions make the road almost impassable by any vehicle other than a six-wheeled Unimog,” says Claassen. “There is intense vibration and tilting of the cargo on these trailers, so our design and bracing is done with this in mind.”
