Photovoltaic DC cables are characterized by UV resistance, high and low temperature resistance, aging resistance, high mechanical strength, and excellent electrical performance, and are specifically designed for long-term outdoor operation of solar power systems.
These cables typically use tin-plated copper conductors to effectively prevent oxidation and ensure conductivity stability. The insulation and sheath materials are mostly cross-linked polyolefin (XLPE) or low-smoke halogen-free materials, cross-linked by electron beam irradiation, possessing excellent weather resistance and flame retardancy.
Their typical operating temperature range is -40℃ to +125℃, allowing them to withstand extreme climatic conditions, and their service life exceeds 25 years, matching the design life of photovoltaic power plants.
Furthermore, photovoltaic DC cables must pass international certifications such as TÜV 2Pfg 1169/08.2007 to ensure safe operation under high DC voltages (e.g., 1800V).
