Our dual-rated XHHW/SIS wire consists of a single Class K-stranded conductor made of tin-coated copper. Its VW-1 rating makes it suitable for switchboards, control panels, automobile factories, programmable logic controllers (PLCs), variable frequency drives (VFDs), and other industrial applications.
Single conductors are available in solid or stranded and annealed or hardened configurations. Tin coated copper conductors are standard in SIS constructions.
Conductors are insulated with a concentrically applied grey XLPE (crosslinked polyethylene) that is VW-1 flame and “Oil and Gasoline Resistant I” rated. An optional non-VW-1 flame rating is available on request. CT (FT4) rating in sizes #1/0 and larger is also available on request.
All black insulation is rated “Sunlight Resistant.” All colored insulation is rated “Sunlight Resistant” in sizes #6 AWG and larger, and optional in sizes #8 AWG and smaller.
Print legends on the wire include the manufacturer, conductor size, voltage rating, UL symbol (if applicable) and type designation. Standard length spools are 500 or 2500 feet.
