Envirotran Three-Phase Pad-Mounted Transformers

3ph_EF_pad.jpg

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 45 - 10,000kVA, in primary voltage classes of 15 kV, 25 kV and 35 kV.

kVA 45-10,000
Primary Voltage Up to 34,500 V
Secondary Voltage 208-14,400 V
