About Pennsylvania Transformer Technology, LLC.
Pennsylvania Transformer Technology (PTT) traces its roots to 1929 in Canonsburg, Pennsylvania, where the company now occupies a 1-million-square-foot, 18-building campus on 90 acres — a site that previously housed McGraw-Edison and Cooper Power Systems transformer operations. PTT designs and manufactures oil-filled power transformers ranging from 500 kVA to 750 MVA with voltage ratings through 765 kV, including generator step-up, autotransformers, pad-mount, unit substation, mobile, and specialty industrial transformers. The Canonsburg facility features North America’s largest GEORG automatic core cutting and stacking line, a 200,000-square-foot tank fabrication bay, 500-ton lifting capacity, and test capability to 765 kV/2400 kV BIL. Beyond new builds, the Power Solutions division provides full lifecycle services: field installation, preventive maintenance, oil processing, repairs, refurbishment, engineering studies (loading, cooling, condition assessment, life extension, stray flux), and authorized replacement parts for load tap changers and circuit breakers from legacy brands such as McGraw-Edison, Cooper Power, and Federal Pacific. The Green Core division handles transformer decommissioning and recycling nationwide. The company serves electric utilities, data centers, renewable energy developers (solar, wind), battery energy storage systems (BESS), heavy industrial manufacturing, and power generation. Its transformers are deployed in utility substations, hyperscale data centers, and grid-integration projects for renewables and storage. PTT emphasizes its nearly 100 years of continuous transformer engineering, dual U.S. production sites, ISO 9001:2015 with Design certification, and the backing of Quanta Services as factors that differentiate it from overseas suppliers and enable support for large-scale infrastructure projects.
