Waukesha® Transformers are Synonymous with Quality and Reliability

Made in the USARecognized as one of the largest manufacturers of power transformers in the United States, SPX Waukesha designs, manufactures and tests its transformers at the company’s modern operating facilities in Waukesha, Wisconsin and Goldsboro, North Carolina according to the latest IEEE, ANSI, NEMA and ISO 9001:2008 quality system standards. The quality and reliability built into every unit we manufacture is the result of over 40 years experience in the design and production of power transformers for utility and industrial applications.

Computer-based, optimized designs and CAD/CAM techniques, coupled with highly trained design and development personnel, help ensure that Waukesha® quality, reliability and peak performance characteristics are built in from the start. Both transformer manufacturing plants utilize sophisticated, computer-controlled equipment and test systems complemented by a well-trained, experienced work force to produce high quality power transformers that meet even the most stringent customer specifications. Before, during and after the sale, SPX Waukesha sales, traffic and service teams respond quickly to customer delivery and installation requirements.
