Type W is an industrial-grade, heavy-duty portable power cable designed for applications that require high-amperage current and extreme durability. Rated for up to 2000V, Type W is built to withstand the most punishing environments, including mines, quarries, and large-scale construction sites. Unlike SOOW or other service cords, Type W does not include an integrated green ground wire; instead, it is a multi-conductor power cable designed for use in systems where the equipment is grounded by other means or where a separate ground is provided. Featuring a dual-layer jacket—typically a reinforced mold-cured Neoprene or CPE—Type W is virtually indestructible, resisting impact, abrasion, flame, and prolonged immersion in water or oil.
Installation Note: Type W cable is designed for "Extra Hard Usage." Because it is an ungrounded cable (it does not contain a dedicated green ground conductor), it must be installed in accordance with NEC Article 400 requirements for grounding and bonding. When terminating Type W in high-vibration environments, ensure you use heavy-duty compression lugs and proper strain relief connectors (such as Kellems grips) to prevent the weight of the cable from pulling on the internal terminations. Always inspect the jacket for deep cuts before each deployment, especially in mining applications where the cable is frequently dragged over sharp rocks.
