PEAK Single-Phase Pad-Mounted Transformer


PEAK™ transformers from Eaton are uniquely designed to allow you additional capability to manage increased loads and temporary overload capacity without loss of life expectancy when compared to mineral oil-filled transformer alternatives.

Utilizing an advanced high-temperature insulation system approach — comprised of thermally upgraded kraft paper, Envirotemp™ FR3™ dielectric fluid, and an optimized core and coil design — a 75 °C Average Winding Rise (AWR) PEAK transformer results in a smaller footprint and a lighter unit capable of the same ratings as a physically larger 65 °C AWR rated unit.

Ratings 10-167 kVA
Average Winding Rise (AWR) 75 °C
Average Winding Rise (AWR) Slash Ratings 55/75 °C and 65/75 °C
Overload Capacity At Least 109%
Approx. Weight (lbs.) 390 (10 kVA) to 1600 (167 kVA)
