DMC Power

What DMC Power does

DMC Power, LLC, founded in 1938 and headquartered in Carson, California, designs and manufactures permanent connector solutions for high-voltage and extra-high-voltage (EHV) power transmission and substation infrastructure. Its core offering is a patented 360° radial swage connection system in which hydraulic tooling applies up to 85 tons of symmetrical force around a connector barrel, producing approximately 20% area reduction and creating connections rated up to 765kV. The product portfolio includes substation bus, cable, and grounding connectors, full-tension transmission connectors for AAC, ACSR, ACCC, and ACSS conductors, and a matched hydraulic tooling line with power units, head assemblies, dies, and pumps. Supporting services include on-site field training, factory-certified repair, custom connector engineering, and a flexible tooling rental program with weekly, monthly, and quarterly billing.

The company sells primarily to electric utilities, renewable energy developers, rail operators, industrial facilities, mining operations, and data center infrastructure operators through a direct enterprise field-sales model supported by dozens of Territory Managers across North America and an online quote-request catalog. Products are priced on a quote basis and manufactured in ISO 9001:2015-certified facilities in Carson/Los Angeles and Olive Branch, Mississippi, with additional service centers in New Castle, Delaware and Roseville, California, plus distribution partners in Australia, New Zealand, Malaysia, Canada, Chile, Mexico, the UAE, and the UK. DMC Power was acquired by Hubbell Incorporated from an affiliate of Golden Gate Capital in October 2025 for $825 million and now operates as a wholly-owned subsidiary of Hubbell.

Expansion highlights5 records

Broad incumbents

• Eaton:
• Hubbell Power Systems: Hubbell Power Systems is the utility-focused division of DMC Power's new parent company, offering transformers, switchgear, insulators, and other T&D equipment. As a broad incumbent with deep utility relationships and a much larger product portfolio, Hubbell Power Systems surrounds DMC Power's niche with adjacent categories.
• Thomas & Betts (ABB): Thomas & Betts, now part of ABB, manufactures electrical connectors, fittings, and components for industrial, commercial, and utility markets. Its broad product portfolio and ABB's global scale make it a broad incumbent competing with DMC Power across multiple utility and industrial customer segments.

Direct peers

• Preformed Line Products: Preformed Line Products (PLP) manufactures hardware for overhead transmission and distribution lines, including deadends, splices, and guy grips. PLP serves the same electric utility customers as DMC Power and offers overlapping product categories in full tension transmission hardware.
• MacLean Power Systems: MacLean Power Systems designs and manufactures transmission, distribution, and substation hardware for electric utilities, including connectors, insulators, and structural products. Its utility-focused product portfolio and direct utility sales model make it a close peer to DMC Power in the T&D hardware market.
• Burndy (Hubbell): Burndy, now a Hubbell brand, manufactures compression and mechanical connectors for power utilities and is the leading incumbent alternative to DMC's swage system. As a sister Hubbell brand, Burndy represents both an internal product-line peer and DMC's most direct competitive comparison in substation and transmission connector markets.
• AFL (Fujikura): AFL manufactures power cable connectors, accessories, and related tooling for the utility and telecom industries, with overlapping product categories in transmission and substation hardware. AFL's power utility segment competes directly with DMC Power's swage connectors across utility customer accounts.
