Decades of Experience

International Transformers, was founded by Ernest Lee in the 1930s and became one of the main UK specialist manufacturers within the industry. With a world-wide range of well-known customers including the Ministry of Defence (MOD), British Aerospace, Alstom, UKAEA/BNFL, BP and others.

Stewart Transformers began as a small operation supplying transformers to the London radio repair sector, just prior to the second world war. During the war the still fledgling company was called upon, as part of the war effort, to supply transformers to the naval arm of the Ministry of Defence, starting a relationship which was set to continue and strengthen for decades.

​

Over the years the Company developed a sound reputation as a specialist manufacturer of transformers and reactors. The company has also expanded from its traditional markets of railways, shipbuilding, defence, semiconductor and high voltage testing to embrace requirements for the utility industries.

Transtech Transformers was founded in the mid-1970's, as part of a group of companies supplying high volume, custom-built transformers. Transtech developed a range of transformers from 1VA single phase to 100kVA three phase, double wound with voltages up to 650 Volts, including toroidally wound components, ferrite assemblies and resin encapsulated units.  Transtech also developed a range of battery chargers, principally for the refrigeration, mobility and leisure industries.
