ELSCO Transformers

ELSCO Transformers, originally known as the Electric Service Company, is an electrical equipment manufacturing and service company founded in 1912 by a team of former Westinghouse engineers led by John F. Shoemaker. Headquartered in Cincinnati, Ohio, the company established the first independent transformer repair facility in the United States to service Westinghouse units. After decades of operating primarily in repair and rewinding, ELSCO began manufacturing its own proprietary line of dry-type transformers in 1988. The company is currently led by President and CEO Todd Benadum and Alan Ober, Vice President of Manufacturing and Engineering. Business/Product Breakdown ELSCO Transformers specializes in the design, manufacturing, and repair of medium-voltage electrical transformers, serving utility, industrial, and commercial sectors. The company's primary manufacturing focus is on new dry-type transformers, ranging from 500 to 2,500 kVA, which are engineered with copper windings and high-grade Nomex insulation to ensure fire safety in indoor environments. Its product catalog also includes oil-filled padmount units, unit substation transformers, and station-type transformers. A core component of ELSCO's operations is its "quick ship" and emergency replacement service, which dispatches in-stock units within 24 to 48 hours to minimize facility downtime. Beyond manufacturing, the company provides technical services such as custom bus work, retrofitting new units into existing enclosures, transformer rewinding, and the sale of certified pre-owned or refurbished units. These solutions are designed to support critical infrastructure in facilities such as hospitals, universities, data centers, and manufacturing plants.
