Powercentres
Product description
By combining our TMD or TCS Load Centre with our Dry Type Power Transformer and THVC Switch, B&F can offer a ‘one box’ solution to your power utilisation needs.
Roadheader/ Continuous Miner Systems, Longwall Coal Faces, Water Pumping Systems, Conveyor Systems and Underground Ventilation are all applications for our Power Centres.
B&F innovated the multi-contactor Load Centre concept over 30 years ago, and have a proven track record with a large global installation base of these units. Simple, rugged and reliable technology is employed to reduce potential down-time and therefore reduce cost of ownership.
Key features
The Power Centre is designed to supply multiple utilisation loads (typically at 550V, 1100V or 3.3kV) from one or more 3.3kV, 6.6kV or 11kV feeder supplies.
A THVC switch controls and protects the incoming supply to the power transformer. The voltage is then stepped down to the utilisation level in the transformer. Finally, the Load Centre’s multiple utilisation outputs feed the individual LV loads, with dedicated and sensitive protection for each output.
This provides a simple and ‘clean’ solution with a minimum of cabling, as all connections to the transformer are accomplished inside the Power Centre itself.

Completed Projects
Svea Nord Longwall Mine
Mining in any part of the world means a harsh environment for the mechanical and electrical plant to be deployed. This is especially true in the Arctic Circle
Adriyala Mine
B&F supply Full Electrical Package for Asia’s biggest Longwall Coal Mine from Design through to Commissioning.
Aberpergwm Mine
Although mining in the UK has declined dramatically over the past thirty years, it would be a mistake to say that there are no more coal mines!
Maintenance
All Baldwin and Francis equipment is designed with ease of maintenance in mind. We offer several maintenance solutions to suit your specific means.
