Photovoltaic Cables

Photovoltaic (PV) cables are the transmission medium for solar power generation systems, specifically designed for outdoor environments with high radiation and extreme temperature variations. Their function is to transmit direct current (DC) energy while resisting corrosion from ultraviolet radiation, ozone, and humidity. The internationally accepted standard is TUV 2 PfG 1169/08.2007, and the corresponding domestic standard is GB/T 33594-2017, ensuring the safe interconnection of photovoltaic power plants.
