Envirotran single-phase overhead transformer
Eaton’s Cooper Power series single-phase Envirotran overhead transformer offers an environmentally responsible, cost-effective, highly efficient and safer choice in overhead transformers. Utilizing 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.
Readily biodegradable and non-toxic, Envirotemp FR3 fluid provides sustainable performance at a low cost
Fluid conforms to ASTM D6871-03 and to pending IEEE PC57.147
Meets or exceeds industry standards including ANSI, NEMA and DOE Energy Efficiency
Constructed with EPRI-recommended interlaced core-type design for greater resistance to low-side voltage surges
Quality System ISO-9001 certified
Available in single- or double-bushing covermount configuration, with secondary voltages of 120/240, 240/480 or 277
Thermoset polyester low voltage bushings provide more temperature resistance than standard polymer
Tin-plated high- and low-voltage bushing terminals accommodate aluminum or copper conductors
The safer, environmentally friendly choice
Utilizing Envirotemp FR3 high-fire-point dielectric fluid, these transformers enhance fire safety while providing environmental benefits. Because the fluid is readily biodegradable and non-toxic, Envirotemp provides sustainable performance at a competitive cost.
Optimum field performance
Eaton’s transformer cores and coils are designed and manufactured to provide the most reliable performance and the industry’s lowest failure rate. Advanced quality management, combined with exhaustive testing, assures unparalleled reliability and operation.
