Envirotran Single-Phase Pad-mounted Transformers


Envirotran™ transformers offer an environmentally responsible, high efficiency, safer choice. The units have high-fire-point fluid, providing fire safety benefits, and a projected life well beyond that of a traditional mineral-oil transformer. These efficient and cost-effective transformers use Envirotemp™ FR3™ fluid.

Envirotran transformers are manufactured in 10-167 kVA, in primary voltage classes of 15 kV, 25 kV and 35 kV. They are available in ANSI Type 2 (Shrubline) or Type 1 (MaxiShrub) configurations.
