Three Transformer manufacturer and repair

In addition to our manufacturing services we also offer a full rewind service. With over 35 years of handling emergency and non-emergency repairs we have built up a wealth of experience. Our rewind facility has the capability to rewind single and three phase transformers. Our facility is ideally to positioned to service the whole of the UK. 

Transformer rewinding, although sometimes more expensive than purchasing a new transformer, may be the only option due to obsolescence. Furthermore, a three phase transformer rewind may have a shorter lead time than a manufactured item.

Three phase transformer enclosures

Single Phase Transformer Enclosure

With our experience we have found that each transformer specification is unique. For this reason we offer a full range of three phase transformer enclosures. Depending on your requirements our transformers range can be supplied with or without an enclosure.

Each enclosure can be custom made to meet your precise requirements. We offer ATEX / EXd enclosures suitable for gas and dust environments, but we can also supply standard IP23 enclosures. All transformer enclosures can be produced from stainless steel or aluminium depending on your specification.


Case studies

Repair of 750kVA transformer

Our team attended our client's site to remove a three phase 750kVa transformer; which required one of the phases to be rewound. This was achieved with 2 day turnaround to ensure production was up and running as soon as possible.

100kVA isolation transformer

Our team designed and manufactured a three phase, 100kVA isolation transformer, designed to be used within a UPS system with customer specified MCCB protection and in a Delta/Star configuration. Our team have also manufactured a range of transformers to the same specification ranging from 10kVA up to 200kVA.

Transformers - defence contract

We enjoy a strong relationship with BAE Systems, which sees us regularly undertake large-scale project work for their operations. In 2009 R Baker (Electrical) Ltd manufactured key electrical transformers for The Queen Elizabeth class super carriers, which are expected to enter service in 2016 and 2018. We also manufactured fuse panels for HMS Ocean and the Khareef class Corvette project. By working in close partnership we offer BAE Systems a high level of service, from design, to development and manufacture.
