4mm² PV DC Solar Cable (Red & Black Pair · 100M per Coil)
4mm² PV DC Solar Cable · Red & Black Pair (100m Coil)
Product Overview
This 4mm² PV-dedicated DC solar cable uses a fine-stranded tinned copper conductor with double cross-linked polyolefin (XLPO) insulation, supplied in matched red/black pairs (positive/negative), 100 meters per coil. Rated for high and low temperatures, UV and ozone exposure, it is halogen-free and flame retardant — engineered for the DC side wiring between PV modules, combiner boxes and inverters, and built to endure harsh outdoor environments for the life of the plant.
Key Features
- PV-dedicated design: built for DC-side operating conditions — module series/parallel wiring, string-to-combiner and combiner-to-inverter power transmission;
- Red & black pair: red/black for positive/negative polarity — fewer wiring mistakes on site, faster installation;
- Tinned copper conductor: fine-stranded tinned copper for excellent conductivity, oxidation and corrosion resistance, easy bending and termination;
- Double insulation: XLPO insulation plus sheath — high dielectric strength and abrasion resistance;
- All-weather durability: -40℃~+90℃ operating range, UV and ozone resistant, hydrolysis resistant — no chalking or cracking in long-term outdoor service;
- Safe & eco-friendly: flame retardant, halogen-free low-smoke — no toxic corrosive gases in case of fire;
- Long service life: designed per PV industry practice for up to 25 years, matching the plant lifecycle;
- Coil supply: delivered in 100m coils — easy to cut with low waste; custom lengths available.
