PEAK single-phase 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 single-phase transformers can be loaded continuously 9% beyond full rated base load.
Improve reliability
With superior moisture and thermal stress managing capabilities, PEAK transformers extend insulation system life, improving overall system reliability by reducing outages and transformer failures.

This brochure outlines Eaton’s Cooper Power series broad commercial and industrial medium-voltage transformer, switchgear, fuse, sectionalizer, switch, regulator, tool, OEM equipment, cable accessory, lightning arrester, power capacitor and recloser offerings.
This brochure describes why Eaton’s Cooper Power series PEAK transformers are uniquely designed to provide additional capability for managing increased loads and temporary overloads without accelerating loss of insulation system life when compared to mineral oil-filled transformer alternatives.
Eaton’s Cooper Power series product team works together with the engineering services team to provide a full storm response procedure to quickly ramp up operations in anticipation of storm impact for fast product shipment and remediation of damaged apparatus during storm recovery.
This catalog provides ratings and ordering information for Eaton’s Cooper Power series single-phase PEAK transformers which are available as conventional (5-167 kVA), completely self-protected (CSP) (5-75kVA) or MagneX interrupter-protected (5-167 kVA).
These instructions have been prepared to assist competent technicians in the installation, operation and service of Eaton's Cooper Power series single-phase overhead distribution transformers.
This specification covers the electrical and mechanical characteristics of Eaton’s Cooper Power series 5–167 kVA single-phase overhead type distribution transformers.
