With the acceleration of China's investment in new energy, the wire and cable industry has begun to recover slowly, and the overall development trend is still rising.

The wire and cable industry's dependence on copper has never changed. The national standard stipulates that electrolytic copper should be used for the copper conductor of the power cable, which has a high purity.

Photovoltaic cables are often exposed to sunlight, and solar systems are often used in harsh environmental conditions such as high temperatures and ultraviolet radiation. In Europe, the on-site temperature of solar systems is as high as 100°C on sunny days.

Copper rod is the main raw material of cable industry, and there are two main ways of production - continuous casting and continuous rolling method and up-drawing continuous casting method.

1, insulation layer: the cable has a specific function of withstand voltage insulation material components.

1. Conductor: A component in a cable that has a specific function of conducting current.
