( SOLAR PV WIRE ) UL 4703 Solar PV wire is one such cable. It is ozone, UV, and moisture resistant cable used for interconnection wiring in photovoltaic systems. It is a durable cable rated at 90°C wet and up to 150°C in dry applications. It can be rated to 600, 1000, or 2000 volts. PV Wire can be used as underground service entrance wire, and is appropriate for both grounded and ungrounded PV arrays. PV Wire meets UL Standard 4703.( RoHS Compliance ): RoHS compliance means that the cable is free of hazardous substances, making it even greener! Choosing solar power cables designed with non-hazardous materials puts an environmentally friendly cable in an environmentally friendly application, and it doesn’t get much better than that! ( APPLICATIONS ): Type Photovoltaic copper conductors are suitable for outdoor rooftop applications without conduit and for use in conduits and raceways installed underground in conduit in wet locations, and where condensation and moisture accumulations within the conduit do not exceed 90ºC. Applications requiring direct burial is permitted for Type Photovoltaic per UL-854. Applications requiring type Photovoltaic conductor, temperatures shall not exceed 90ºC in wet or dry locations. ( FEATURES ):Available in 600V and 1000V/2000V. All cables comply with UL’s VW-1 (Vertical Wire) Flame Test. Insulation compounds are rated for flame and sunlight-resistance in all sizes and colors. Photovoltaic conductors of 1/0 through 1000 KCMIL are rated for CT use. Sequential foot markings located every foot on master reels only for 1 AWG through 1000 KCMIL unless otherwise specified.RoHS compliant. Flexibility at Low Temperature Test. Carries -40C rating.
