A 6 sq mm solar string cable is a specialized, single-core DC cable designed for connecting solar panels in photovoltaic (PV) systems. These cables are built for durability and high performance in harsh outdoor conditions, featuring tinned copper conductors and UV-resistant, electron-beam cross-linked (XLPO or XLPE) insulation and sheathing. Key Descriptions and SpecificationsThe key features and technical specifications of a typical 6 sq mm (square millimeter) GTP (likely a brand/type, e.g., Polycab GTP, Apar GTP) solar cable include: Conductor: Fine wire strands of annealed, tinned copper (Class 5 flexibility as per IEC 60228) for high conductivity and flexibility. The tin coating prevents corrosion.Insulation Sheath: The cable typically uses double insulation, with an inner insulation and outer sheath made of electron-beam cross-linked polyolefin co-polymer (XLPO) or cross-linked polyethylene (XLPE). This material is halogen-free and provides enhanced safety.Environmental Resistance: It is designed to be highly resistant to ultraviolet (UV) radiation, ozone, weather conditions (rain, dust, temperature variations), oils, and chemicals. Regular PVC cables would become brittle in the sun, so this UV protection is crucial.Voltage Rating: Commonly rated for up to 1.0/1.0 kV AC or 1.5/1.5 kV DC nominal (up to 1.8 kV DC maximum).Temperature Range: Capable of operating in extreme temperatures, typically from -40 C to +120 C.
