PEAK single-phase pad-mounted transformer
Eaton’s Cooper Power series single-phase pad-mounted PEAK transformers provide the capability to manage increased loads and temporary overload conditions without accelerating loss of insulation system life compared to mineral oil-filled alternatives. The transformer's overload capacity enables utilities to operate beyond full rated load to at least 109%, while their smaller, lighter footprint further enhances value. Available in ratings from 10-167 kVA, the transformers are available in MaxiShrub, Shrubline and Ranch Runner designs to meet various applications.
Voltage Class
MaxiShrub & Shrubline: 10-167 kVA; Ranch Runner: 10-50 kVA
AWR Slash Ratings
55/75 °C and 65/75 °C
Average Winding Rise (AWR)
75˚ C
Core features
- PEAK transformers are a class of transformer technology designed to improve performance in terms of kVA rating, compact dimensions, lighter weight, safety and sustainability.
- Utilizes an advanced high-temperature insulation system comprised of thermally upgraded kraft paper, Envirotemp FR3 dielectric fluid and an optimized core and coil design
- Superior moisture and thermal stress managing capabilities allow for extended insulation system life and enhanced reliability
- Available in 10-167 kVA single-phase pad-mount designs; 75 °C AWR and 65/75 °C AWR options
- 75 °C Average Winding Rise (AWR) of PEAK transformer offers same ratings as a physically larger and heavier 65 °C AWR rated unit
- A 65/75 °C slash rated PEAK transformer is comparable in size to a conventional transformer but has nameplated overload capability
- Meets or exceeds industry standards including ANSI, NEMA and DOE Energy Efficiency (except Ranch Runner frontplate)
- Available in conventional or CSP designs for various overcurrent protection options
- Available in MaxiShrub with an ANSI Type-1 frontplate, Shrubline with an ANSI Type-2 frontplate for a lower profile for improved aesthetics, or Ranch Runner with a Rural Utilities Services (RUS) approved frontplate for a more compact, economical design
- Cores and coils designed for high reliability and low field failure rates: Available in grain-oriented electrical or amorphous steel
Gain additional load capacity
Designed to accommodate heavier base loading for longer periods without accelerating loss of insulation system life, PEAK pad-mounted transformers can be loaded continuously 9% beyond full rated base load.
