Material & Design
Material Selection
Conductor: Adopts high-purity oxygen-free copper (OFC) with excellent electrical conductivity, low resistance, and minimal power loss.
Insulation: High-density cross-linked polyethylene (XLPE) or EPR insulation provides superior electrical insulation performance, high temperature resistance, and resistance to aging.
Sheath: The thermoplastic elastomer sheath offers exceptional flexibility, wear resistance, UV resistance, and chemical resistance.
Structural & Appearance Design
Structural Design: The cable features a compact stranded conductor structure, which improves flexibility and facilitates easy installation in tight spaces.
Appearance: Standard color options include black and red/black paired cables.
Advantage Of Solar Cable
Broad Compatibility: Seamlessly integrates with residential, commercial, off-grid, and portable PV systems.
Harsh Environment Resilience: Engineered to withstand coastal corrosion, desert high temperatures, and high-altitude UV/low-temperature exposure.
Reliable Power Transmission: Ensures stable connectivity between solar panels, inverters, and battery storage units.
Material Flexibility: Tinned copper option available for enhanced corrosion resistance in demanding settings.
Application Of Solar Cable
