Dura-Flex® Type W

Portable Power Cable

Direct’s Dura-Flex Type W cable is a highly durable, flexible portable cable primarily used for permanent or temporary power supply. The versatile cable is commonly terminated with Cam-Lok™ connectors and other power connector types to construct various power cable assemblies, feeder cables, and cable extensions.

Dura-Flex Type W cable is typically deployed within heavy-use, industrial, and emergency applications, including power and equipment rental (e.g. power generators), motor and battery leads, mining and oil drilling, shore power, HVAC systems, and general power distribution.

Dura-Flex Type W cable is UL and cULus listed, CSA approved, RHH / RHW / RHW 2, RoHS compliant, and manufactured in the USA.
