What is the difference between photovoltaic cables and ordinary cables?

Photovoltaic cables are often exposed to sunlight, and solar energy systems are often used in harsh environmental conditions such as high temperature and ultraviolet radiation. In some areas, when it is sunny, favorable terrain will cause the on-site temperature to reach 100°C. In such places, we can use our photovoltaic cables.

The characteristics of photovoltaic cables are selected by their special cable insulation and sheath materials, called cross-linked PE. After irradiation by irradiation accelerator, the molecular structure of the cable material will change, thereby providing its various functions. Mechanical load resistance is during installation and maintenance. The cable can be routed on the sharp edge of the roof structure. At the same time, the cable must withstand pressure, bending, tension, cross-tensile loads and strong impact. If the cable sheath strength is not enough, the insulation layer of the photovoltaic cable will be severely damaged, which will affect the use of the entire cable and eventually cause irreversible consequences.

Photovoltaic cables are mainly copper conductors or tinned copper conductors, irradiated cross-linked polyolefin insulation. Ordinary cables are also copper conductors or tinned copper conductors, but are insulated with polyvinyl chloride or cross-linked polyethylene. The conductors used are the same, but there are still big differences in cable insulation and sheath. Ordinary cables can be used in ordinary environments, but photovoltaic cables can be used in harsh environments.
