Listen to this article

For over 35 years, Electro-Wind engineers have been designing and manufacturing single and three-phase transformer products for customers across the globe.

With a well-established reputation, the company has fulfilled many contracts for companies including Alstom, Tata, Corus, Mitsubishi, Siemens, and Toyota.

In early2016, Electro-Wind was approached by Devontech to work as its main transformer supplier to design, build, and obtain approval for a range of PSP transformers for the Feltham and Wokingham re-signalling project.

Between them, the Feltham Area Signalling Centre and Wokingham Signal Box cover 80 miles of railway and 500 separate pieces of signalling equipment on key areas of the South Western Railway (SWR). Dating back to 1974, the existing equipment which includes signals, the traffic light system for the railway, and track circuits, is becoming increasingly difficult to maintain. Electro-Wind, Devontech, and Atkins global have been working on the project which is part of Network Rail’s commitment to transform the entire UK network through the deployment of digital signalling and train control Technology.

To date, Electro-Wind has manufactured 57 transformers for the project ranging from 5kva up to 60kva. The transformers have been 400v/650v signalling transformers on which Devontech and Electro-Wind worked closely together to get PADS approval for the Network Rail Infrastructure. 

The project, which began in December 2015, is due for completion in March 2023. There have been five phases: phase one, in the Strawberry Hill area, was completed in Easter 2021; phase two, Virginia Water and Ascot, was completed in Easter 2022; phases three and four, in the Windsor, Staines, Feltham and Kew Bridge areas, are expected to be completed in August 2023. Finally, phase five, in the Wokingham area, is expected to be complete in February 2024.

The project is currently running on schedule, with final commissioning for the project into service in April 2024.

Electro-Wind’s expertise and capabilities in the coil winding industry allow it to manufacture any bespoke transformer from 10VA up to 2MVA, in addition to AC reactors, DC rectifiers and chokes, with a comprehensive range of associated products including site electrical accessories on offer.

The company also provides a rapid response repair service, from new enclosures to complete rewinds, and can offer a 24-hour service when needed.
