Isolation Transformer

R Baker (Electrical) Ltd design and manufacture a full range of reactors, which help keep your equipment running longer by absorbing many of the power like disturbances which otherwise damage or shut down your inverters, variable speed controllers or other sensitive equipment.

Our Reactor Range

Our in-depth understanding of different applications of reactors enables us to rewind and manufacture to any specification you may require, our range of chokes & inductors can be custom made and are utilised across a wide range of sectors including, Rail, Switchgear, and Offshore sectors.

Our Electrical Engineering Team work out of our purpose built manufacturing facility, specialising in designing, modifying and reverse engineering to your reactor specification. All our manufactured reactors can be supplied with full working drawings, component lists and written instructions in any language.

All our quality standards and procedures are monitored independently to BS EN ISO 9001:2000 and are subject to regular external and internal audits. We also work with all the leading testing and quality authorities such a BSI, DNV, Lloyds, NSN, Nemko and VDE to give you total peace of mind.

Case Studies

Aluminium Reactors

Our client requires a full repair and rewind service on two different types of aluminium transformer and reactors. Our Engineering Team carry out a full survey and repair service working to the highest standards to meet rail industry requirements. 


Control panelArmature rewinds 

Working closely with our customer we were able to offer a custom built test panel. This required a complex system which offers the facility to test faults in long lengths of cable. This system required our in-house team to manufacture a large air-choke; to restrict the fault current to specific level for levels required for this test.
