Eaton’s Cooper Power series single-phase Envirotran overhead transformer offers an environmentally responsible, cost-effective, highly efficient and safer choice in overhead transformers. Utilising Envirotemp FR3 high-fire-point dielectric fluid, these transformers provide fire safety benefits coupled with a projected lifespan well beyond that of a traditional mineral-oil transformer. Envirotran transformers are manufactured in 5-167 kVA models.
