UK-based Distribution Transformer Manufacturers

Powerstar was incorporated in 2001 and since then, built a global reputation for the high-quality manufacture of bespoke solutions that provide tangible energy and cost saving benefits for clients.

Powerstar’s flagship solutions include Powerstar voltage optimisation, VIRTUE energy storage solutions and most recently the Powerstar SO-LO range of super low loss smart transformers.

In 2017, Powerstar acquired Bromsgrove Winding Services, an established and renowned original equipment manufacturer (OEM) of custom-built power and distribution transformers and reactors with a strong heritage of successful projects in a wide range of industries and applications throughout the world. It still operates in Bromsgrove under the Powerstar brand and since the integration of the business, it has expanded its product portfolio.

The company prides itself on being the only UK manufacturer of amorphous core distribution transformers and believes firmly in providing the highest level of customer service, client support and efficiency of production. Powerstar offers quick and flexible turnaround on orders and a 24-hour breakdown service, available 365 days per year.

Additionally, it is proud to uphold the highest quality standards across its entire range of products and conforms to numerous manufacturing approvals.
