PEAK Single-Phase Overhead Transformer

peak-pole-transformer-220.jpg

PEAK™ transformers from Cooper Power Systems 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 5-167 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.) 220 (5 kVA) to 1350 (167 kVA)
