Substation & Power Transformers

Medium- and high-voltage units, built to project spec

Made-to-order liquid-filled substation and power transformers for utility interconnection, large industrial loads, and multi-megawatt data-center sites.

Each unit is engineered to the project's specification (voltage class, impedance, taps or on-load tap changer, accessories, and losses) and passes a full routine-test program in a CNAS-accredited transformer test station before it ships.
