Envirotran Substation Transformers

Unit_Type_Sub.jpg

Envirotran™ transformers are the industry’s first transformers to use an edible vegetable oil-based, high-fire-point dielectric coolant. This technological and environmental design breakthrough is the result of years of research and development in dielectric fluids and their use in 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.
