Our Customers


First of four new winding machines to arrive at Winder Power, currently being installed.

Probably the only UK transformer manufacturer still winding and assembling 33/11kV primary transformers in house.

Two days ago our substation services team finished installing this 12/24MVA 66kV transformer for our local DNO.
They do a fantastic job but unfortunately they’ll be out of action for a few weeks due to site restrictions following the coronavirus. We wish them well.
