Photovoltaic cable is a kind of cable specially used for solar photovoltaic system, which is mainly used to connect photovoltaic modules, inverters, transformers and other equipment to transmit electric energy. Since photovoltaic systems are usually installed in outdoor environments, photovoltaic cables need to have weather resistance, corrosion resistance, abrasion resistance and other characteristics to ensure their long-term stable service life. The conductor part of photovoltaic cable usually adopts copper conductor or tinned copper conductor, because copper has excellent conductivity and corrosion resistance, which can ensure the electrical performance and service life of the cable. At the same time, tin plating can further improve the corrosion resistance of copper conductors, thereby enhancing the durability of cables
