PV Wire carries Direct Burial designation.
Press Release Summary:
Offering protection from sun, ozone, heat, and abrasion, Direct Burial PV Wire utilizes Ethylene Propylene Rubber insulation and Chlorinated Polyethylene protective jacket, which is preferred solution for transformerless inverter systems. Seven-strand bare copper conductor is recommended as it provides optimal contact at combiner box if built-in bulkhead connectors are not utilized. In addition to UL 4703 rev of 11/17/09, wire includes UL VW-1, RHH or RHW-2, UL 44, and UL4703 ratings.
Original Press Release:
USA Solar Cable Leads the Way with Industry's First Direct Burial PV Wire
Approved for use with transformerless inverter systems
USA Wire & Cable has introduced the industry's first PV Wire to carry the Direct Burial designation under the UL 4703 revision of 11/17/09. The cable offers superior protection from sun, ozone, heat and abrasion. The cable utilizes EPR insulation and a separate protective jacket which is the preferred solution for transformerless inverter systems.
Later this year it is anticipated that transformerless inverters will begin making an impact in the US Solar market as the industry continues its drive towards efficiency increases and construction cost reductions.
"Our goal with USA SOLAR CABLE is to always provide industry leading solutions, providing products which adhere to the most recent and stringent code and UL requirements. As UL recommendations for PV Wire evolve, we will provide the cable and connector solutions that meet and anticipate the needs of the US Solar industry." - VP of Sales, Hugh Robertson. "We are seeing projects requiring higher voltage ratings, greater concern for quality and durability and stricter adherence to the 2008 NEC Code and UL standards. We are also beginning to feel some momentum growing for transformerless inverter systems as they begin to be introduced in the US market."
The cable is rated to 2KV with Ethylene Propylene Rubber (EPR) insulation combined with Chlorinated Polyethylene (CPE) jacket. This combination provides advantages over a single thicker layer of Cross-linked Polyethylene (XLP) including improved resistance to damage from sun, ozone, heat and abrasion. The 7 strand bare copper conductor is recommended as it provides better contact at the combiner box if built-in bulkhead connectors are not utilized. Additional ratings include: UL VW-1, RHH or RHW-2, UL 44, UL4703.
