A single, accountable source for North American transformers
We bridge a world-class manufacturer with the standards, logistics and support that US and Canadian projects demand — factory pricing without sacrificing local accountability.
Built to North American codes
Every export unit meets DOE 2016 and CSA 2023 efficiency, with ANSI/IEEE voltage classes and accessories specified for US and Canadian utilities.
Proven export track record
Hundreds of pad-mounted and distribution units already shipped to the United States, Canada and 120+ other markets — from 15 kVA single-phase to 2500 kVA three-phase.
Engineered, tested, guaranteed
Designs validated with Siemens simulation software and proven in a 500 kV test hall. Every transformer is type- and routine-tested and carries a full warranty.
Transformers for every point on the grid
From the substation to the service drop — one supply partner across six product families.
North American specs, not adapted afterthoughts

Trusted where reliable power matters most
What buyers ask us first
Are your transformers compliant with US and Canadian efficiency rules?
Yes. Our export pad-mounted and pole-mounted transformers are built to DOE 2016 efficiency for the US market and CSA 2023 efficiency for Canada, and carry UL and CSA documentation. Distribution and power units are type-tested to IEC and ANSI/IEEE standards.
What voltage and kVA ranges can you supply?
Single-phase from 5–250 kVA, three-phase pad-mounted to 2,500 kVA, distribution to 31,500 kVA, and power transformers from the 110 kV up to the 750 kV class. Primaries include 4.16, 12.47, 13.2, 13.8, 24.94 and 34.5 kV.
Can units be customized to our utility standards?
Absolutely. Our export line is designed to be customizable — taps, impedance, bushings, fusing, loop-feed configuration, paint and monitoring accessories are all configured to your specification.
What about lead time, warranty and support?
Lead times depend on configuration and quantity; we provide a firm schedule with each quote. All products carry a one-year warranty with unconditional replacement for manufacturing defects, plus cost-price spare parts and responsive after-sales support.
