Core features

Better manage temporary overload capacity

PEAK single-phase pad-mounted transformers can be loaded continuously 9% beyond full rated base load, helping utilities to more precisely size transformers based on periods of peak demand, without accelerated reduction of insulation life.

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.

Improve reliability

With superior moisture and thermal stress managing capabilities, PEAK pad-mounted transformers extend insulation system life, improving overall system reliability by reducing outages and transformer failures.
