Solar cables are composed of conductors, insulation layers, sheaths and connectors. Conductors are usually made of high-purity copper or aluminum to ensure good electrical conductivity and current transfer capability. The insulating layer is made of high temperature, UV and oxidation resistant materials, such as polyethylene or polyvinyl chloride, to protect the wires and prevent loss of electrical energy. The jacket provides an additional layer of protection, enhancing the weather resistance and durability of the solar cable. Connectors are used to connect solar modules and inverters to ensure the normal operation of the entire system.

Solar cables are also fire-resistant and able to work in extreme environments, such as areas with high temperature, cold and high humidity changes. At the same time, solar cables also need to have properties such as anti-aging, abrasion resistance and tensile resistance to meet different application requirements.
