PEAK Three-Phase Pad-Mounted Transformer

PEAK-three-phase-pad.jpg

Eaton’s Cooper Power series PEAK™ transformers 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 45 - 12,000 kVA
Average Winding Rise (AWR) 75 °C
Average Winding Rise (AWR) Slash Ratings 55/75 °C and 65/75 °C
Overload Capacity At Least 112%
Primary Voltage 2,400 – 46,000 V
Secondary Voltage 208Y/120 V to 14,400 V
Specialty Designs Inverter/Rectifier Bridge; K-Factor (up to K-19); Solar/Wind Designs; Differential Protection; Seismic Applications (including OSHPD)
