Elite 3300v Variable Speed Drive
Product description
B&F introduced its first 1100V water-cooled Variable Speed Drive (VSD) to the mining market nearly 20 years ago. Since then, our product development programme has resulted in a range suitable for all types of mining applications, with ratings up to 2MW at 3.3KV.
Coal Face Conveyor (AFC), Coal Clearance, Water Pumping Systems, and Underground Ventilation and Skip Controllers are all applications for our VSD units.
The ‘Elite’ 3300V VSD is designed to control an induction motor from standstill up to its full speed, by simple insertion into an MV supply cable (in-line).
An advanced 3-level rectifier, dual-rail DC link and 3-level inverter combine to create the 3-phase output to the motor, with dedicated and sensitive protection for the output. Water cooling is employed to minimize the footprint of the unit.

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
