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.
