Power Transformers

Parts Super Center stocks an exclusively licensed line of OEM renewal parts to extend the service life of Prolec/GE 15-700MVA installed base of Pittsfield transformers and components used in high-voltage transmission and substation applications. Power transformers are designed to step up or step down voltage for efficient long-distance energy transfer, operating at voltage levels typically above 33 kV and supporting large-scale electrical infrastructure.

Browse replacement parts for power transformers, including bushings, radiators, cooling systems, valves, gauges, tap changer components, gaskets, and mechanical hardware used in high-capacity transformer systems. Power transformers are critical for transferring electrical energy between generation stations, transmission networks, and distribution systems. These transformers operate continuously under high-load conditions and are essential for utilities, steel mills, data centers, and industrial facilities that require reliable, large-scale power delivery.

Components support high-voltage transformer systems ranging from medium- to ultra-high-voltage applications, with power ratings typically measured in kVA or MVA to define total load capacity. Transformer capacity is based on apparent power (kVA), which represents the combined effect of voltage and current in the system.  Our inventory supports GE and legacy power transformer systems, helping maintenance teams source hard-to-find and obsolete components for ongoing operations. PSC retains all rights to the drawings and documentation for large power transformers. Whether supporting new infrastructure or maintaining aging equipment, these parts help extend transformer life and minimize downtime.
