What Electrolock does
Electrolock Inc. is a privately held, Ohio-incorporated specialty manufacturer founded in 1957 that designs, converts, and supplies electrical and thermal insulation materials for high-voltage generators, batteries, traction motors, industrial furnaces, and fire-rated cable applications. The company's product portfolio spans six core categories — high-voltage insulation materials and tapes, battery insulation, spiral wound tubing, high-temperature wire and cable insulation, thermal insulation, and polyshrink film — augmented by sub-brands from the Isovolta Group (Poroband, Conductofol, Contafel, Porofab, Calmicaglas) and the proprietary Pyrodox mica cable tape trademark. Operations center on two US facilities: a Hiram, Ohio headquarters and converting plant built in 1969 with an in-house materials laboratory (est. 1981), and a Duncan, South Carolina converting facility opened in 1984 to serve southern states and add capabilities unavailable in Ohio.
The business model is a hybrid of standard catalog products and engineered-to-order custom solutions, executed via a technical sales force that engages customers' engineers to define problems, design solutions, manufacture to specification, and validate through analytical and high-voltage testing. Pricing is quote-based with no publicly disclosed tiers, and customer relationships are characterized by long qualification cycles and 10+ year supplier tenures cited in testimonials from EV motor, battery, superconducting magnet, and busway manufacturers. Go-to-market is direct technical sales supported by a content website, thought-leadership articles, and online calculators, with stated distribution reach into Europe via a raw material partner network.
Revenue is not disclosed. The company holds ISO 9001:2015 certification, maintains no app or public API, has no disclosed funding rounds, M&A activity, or institutional ownership, and reports 11-50 employees. Its AI footprint is limited to a publicly disclosed internal policy governing use of generative AI for marketing content production.
