About Maddox Industrial Transformer
Maddox Industrial Transformer was founded in 2015 by a group of transformer industry veterans led by Camden Spiller in Simpsonville, South Carolina. The company is headquartered in Battle Ground, Washington, and operates seven facilities across the United States, including locations in Greer, Pelham, Fountain Inn, and Woodruff, South Carolina; Batavia, Ohio; Moscow, Idaho; and Houston, Texas. The company designs, manufactures, supplies, and warranties padmount, substation, polemount, and dry-type transformers built to ANSI, NEMA, DOE, and IEEE standards. It also provides pad-mounted and metal-enclosed switchgear. With over 400 employees, the company has shipped more than 100,000 transformers. Maddox serves commercial and industrial customers across data centers, manufacturing, renewables, electrical distribution, bitcoin mining, electrical contractors, and real estate development. Its clients range from family-owned businesses to Fortune 100 companies and global data-center hyperscalers. Case studies reference a lumber mill, irrigation district, city electric utility, and solar project. The company was started to address long lead times and unresponsive service from traditional utility-focused OEMs. Maddox differentiates itself with a "Fast Pass" model for commercial and industrial projects, offering same-day quotes, stock units that can ship in hours, expedited custom production, and direct access to sales engineers rather than call centers.
