This single-conductor photovoltaic (PV) wire is used as interconnection wiring for grounded and ungrounded PV power systems on residential, community, and utility-scale solar projects.
Single conductors are available in solid or stranded and annealed or hardened configurations. Tin coated copper conductors are also available.
Conductors are insulated with a concentrically applied XLPE (crosslinked polyethylene) that is FV-1 flame and “Oil and Gasoline Resistant I” rated. An optional VW-1 flame rating is 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.
