Power & Distribution Transformers

Power Transformers

At Winder Power it goes right to the heart of everything we do. We design, manufacture, deliver and install the electricity power transformers which play a vital part in the country’s infrastructure.

Distribution Transformers

Winder Power designs and manufactures a range of distribution transformers, complying with the requirements of ESI 35-1 and BSEN60076 (2000) as applicable.


Reactors are special transformers that are used widely in AC networks to limit current and to control voltage and load flow.

Factory Refurbishment

We understand the drivers of our customers and what lies behind their asset management plans. We offer a unique, 12 stage power transformer refurbishment service in our modern, state-of-the-art factory.

On-site Refurbishment

Not every organisation is able to take its assets offline even for the time taken to perform a refurbishment, and if minimal outage and disruption is a key consideration then Winder Power can provide an effective on-site refurbishment programme.

Switchgear & Instruments

Winder Power supplies a full range of high quality medium and low voltage switchgear. 

In addition Winder Power can design and manufacture instrumentation and control panels for practically all transformer applications.

Air-Cooled & Cast Resin Transformers

Winder Power manufactures a range of air-cooled, dry type Class 220 insulated transformers, with or without enclosures. They are particularly suitable for use at high temperature and in tunnelling applications.

Eco Transformers

This energy efficiency improvement has already been applied to consumer products such as lightbulbs, vacuum cleaners and refrigerators. It is now also to be applied to medium and large power transformers.
