Heavy-Duty NEMA Industrial Extension Cord — Rugged SOOW/SJEOW, 15A–30A, 10–100 ft

These industrial NEMA extension cords use high-strand copper conductors and a heavy-duty SOOW or SJEOW jacket. The flexible jacket resists oil, water, chemicals and repeated handling in mud, rain, freezing cold and high heat.

Offshore rigs, refineries, shipyards and construction sites need connections that stay secure through a shift. These jobsite-proven connectors use straight-blade or twist-lock plugs for vibration and heavy loads, with molded strain relief or field-serviceable housings for handling around concrete and steel.

Lengths include short 3–6 ft cords for panel tie-ins, 25–50 ft for everyday tools and 100 ft for wider power runs. Conductor options run from 12 AWG for 20A tools to 10 AWG for 30A welders. UL/CSA compliance supports industrial use.

These industrial cord assemblies provide an equipment connection for repeated job-site use, from temporary tool power to longer work-area runs.
