Pennsylvania Transformer

What Pennsylvania Transformer does

Pennsylvania Transformer Technology, LLC (PTT) is a U.S.-headquartered manufacturer of oil-filled power transformers headquartered in Canonsburg, Pennsylvania, operating as a wholly-owned subsidiary of Quanta Services Inc. (NYSE: PWR) following its 2023 acquisition. With roots dating back to 1929 and nearly a century of accumulated transformer expertise through successive ownership by McGraw-Edison and Cooper Power Systems, PTT manufactures high-voltage power transformers ranging from 500 kVA to 750 MVA through 765 kV, including dedicated 345 kV, 138 kV, and 69 kV units. The product portfolio also includes medium-voltage pad-mount transformers (500 kVA to 7,500 kVA), mobile transformers and substations up to 245 kV/40+ MVA via a partnership with Elgin Power Solutions, and EHV shunt reactors up to 150 MVAr through 765 kV.

PTT's technical capabilities are anchored by North America's largest GEORG automatic core cutting and stacking line (840 mm), two high-capacity vapor-phase autoclaves, a 200,000 sq. ft. transformer tank fabrication shop, and a temperature/humidity-controlled winding environment at its 1 million sq. ft. Canonsburg headquarters. A second 56,000 sq. ft. facility in Raeford, NC has been operational since 1992, and a third 150,000 sq. ft. smart factory is under construction in Hoke County, NC ($102.5M investment, Q4 2026 completion, with IoT-enabled robotics and advanced automation). Production is supported by 3D modeling, finite element analysis, vapor-phase drying, and 500-ton overhead lifting capacity, with testing capability up to 2400 kV BIL.

The business model is built on custom-engineered, quote-based capital equipment sales (multi-year contracts), augmented by the Power Solutions Division's recurring parts and field service revenue (40,000+ parts inventory across McGraw-Edison, Cooper Power, Federal Pacific, and Pennsylvania Breaker OEM lines) and the Green Core decommissioning/recycling division. PTT sells exclusively through direct enterprise field sales with dedicated engineering teams, targeting electric utilities, data centers, renewables/BESS, and industrial customers across the U.S. and Canada. The company maintains regional offices in Vadodara, Nagpur, and Mumbai (India) for engineering and customer support. PTT is ISO 9001:2015 with Design certified (Smithers), complies with ANSI/IEEE/NEMA/CSA standards, and holds NMSDC minority supplier certification.
