UL 4703 PV 1000V OR2000V Tin-plated Copper Core Solar Photovoltaic Cable
UL 4703 photovoltaic circuit cable sheath is made of cross-linked polyolefin insulation material, copper core is made of tinned pure copper, double-layer sheath design, wear-resistant, waterproof, oilproof, high temperature resistance, ozone resistance, can more effectively protect the cable, low resistance, low eccentricity, strong flexibility, long service life. Low power consumption, ideal for high-frequency applications. Photovoltaic cables are different from ordinary cables: photovoltaic cables are exposed to sunlight, and solar systems are often used under harsh environmental conditions, such as high temperatures and ultraviolet radiation. The cross-linked material has high mechanical strength, the cross-linking process changes the chemical structure of the polymer, the fusible thermoplastic material is converted to non-fusible elastomer material, and the cross-link radiation significantly improves the thermal, mechanical and chemical properties of the cable insulation material.
UL 4703 photovoltaic wire is UL product certified wire and cable, suitable for photovoltaic power generation system equipment internal and external circuit connection, can meet extreme weather conditions and long-term installation and use requirements, can be widely used in solar power plant photovoltaic system and other fields.
