Name: China Double Insulated Solar Cable Manufacturers Suppliers Factory - Wholesale Service - Huayu Cable
Brand: Huayu Cable
SKU: 314413722

Products Description

Solar cables connect PV panels and carry DC power from the panels to inverters. The "double insulated" part means two layers of XLPO insulation wrap the tinned copper conductor - one inner layer, one outer jacket.
This double layer gives extra protection against UV rays, heat, rain, and temperature swings, so the cable lasts 25+ years outdoors. It's flexible, halogen-free, flame retardant, and works from -40°C to 120°C. Standard sizes are 4mm² and 6mm², red for positive, black for negative.
Commonly used for rooftop solar, utility-scale farms, and any outdoor PV wiring where weather resistance is a must.
