Winder Electrical has recently completed a £1.2m contract to design, build and install some 55 distribution and isolation transformers for 23 separate sites across London. As part of the ongoing development for the Channel Tunnel Rail Link, the project is one of the biggest in the company’s long and successful history.

The transformers range in size from 500kVA to 8MVA and provide the power for ancillary equipment for the crucial second section of the high-speed link. The route runs from Southfleet in Kent to St Pancras via Dagenham including a below-water Thames crossing.
