Description

This 600V UL 4703 PV solar cable is purpose‑built for harsh, long‑term outdoor service, combining fine‑stranded tinned copper conductors with a thermoset cross‑linked polyolefin/XLPE insulation system that maintains electrical integrity under sustained UV exposure, wide temperature swings, and wet or direct‑burial conditions. Optimized for photovoltaic DC circuits, it offers low DC resistance to reduce string losses and supports flexible installation with cold‑weather handling down to −40°C and a typical minimum bend radius of ≥6×OD.

Sunlight‑resistant and flame tested (VW‑1 typ.), the cable integrates seamlessly into NEC Article 690 compliant designs for module interconnects, homeruns to combiners, and inverter inputs across residential, commercial, and utility‑scale projects. Available in 18 through 10 AWG with black as standard and red/custom colors on request, it ships on long continuous reels to speed pulls and minimize splices in the field.
