TWS Energy Controls provides a complete custom design service so you get exactly the right voltage transformer to meet your specific application. We have indoor and outdoor voltage transformers available 12kV, 24kV and up to 36kV.

We provide single, two or three phase units, with one or two secondary windings that can be dual class, i.e. 0.5/3P. The 3.6kV and 6.6kV units can be fully insulated for phase-to-phase operation.

Outdoor Voltage Transformers
