WR Transformers develops, designs and manufactures superior quality transformers at its plant in Granby, Quebec. Operating in a factory of over 50 000 square feet, we build large capacity units up to 20 MVA, voltages up to 49 kV insulation class up to 220kv BIL. With more than a decade of experience in the market, our team offers you excellent technical support and service that will meet your highest expectations.

Our expertise lies in developing and producing custom electrical transformers. Our facility’s versatility and our knowledgeable personnel lend a hand in the planning and making of your next transformer.

WR transformers have been put in place across all five continents and are used to support a wide range of industries – from industrial to commercial, mining to data center, pulp and paper to aluminum smelting, and micro-networks. Other essential domains in which these transformers are used include hospitals, factories, schools, pharmacies, grocery stores and many more, requiring a secure and consistent energy source.

Furthermore, WR has been granted ISO/IEC 17025 certification for our testing laboratory, which is a symbol of quality regarding the capabilities, understanding, and dependability of the personnel and equipment utilized in the test facility. Every single transformer produced by WR is subjected to this intense testing procedure.
