The difference between photovoltaic cables and ordinary cables

Photovoltaic cables are often exposed to sunlight, and solar systems are often used under harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny favorable terrain will lead to on-site temperatures of up to 100°C for solar systems. At present, the various materials we can use are PVC, rubber, TPE and high-quality cross-link materials.

The characteristics of the photovoltaic cable are selected by its special insulating material and sheath material for the cable. We call it cross-linked PE. After being irradiated by an irradiation accelerator, the molecular structure of the cable material will change, and then provide various aspects of it. function.

Resistance to mechanical loads In fact, during installation and maintenance, cables can be routed on sharp edges of the roof structure, while cables must withstand pressure, bending, tension, cross tensile loads and strong impacts. If the strength of the cable sheath is not enough, the cable insulation layer will be severely damaged, which will affect the service life of the entire cable, and may cause problems such as short circuit, fire and personal injury hazards.
