The difference between photovoltaic cables and ordinary cables

       The difference between photovoltaic cables and ordinary cables
　　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, sunny days will cause the site temperature of the solar system to reach 100 ° C. Currently, we can use various Such materials are PVC, rubber, TPE and high quality cross-link materials, but unfortunately, rubber cables rated at 90°C, and even PVC cables rated at 70°C are often used outdoors, and currently The National Golden Sun Project is frequently launched. In order to save costs, many contractors do not choose special cables for solar energy systems, but choose ordinary PVC cables to replace photovoltaic cables. Obviously, this will greatly affect the service life of the system.
　　The characteristics of photovoltaic cables are determined by the special insulating materials and sheathing materials for cables, which we call cross-linked PE. After being irradiated by an irradiation accelerator, the molecular structure of the cable material will change, thereby providing its performance in all aspects. .
　　resistance to mechanical loads
　　In fact, during installation and maintenance, the cables can be routed on the sharp edges of the roof structure, while the cables are subjected to pressure, bending, tension, cross tensile loads and strong shocks. If the cable jacket is not strong enough, the cable insulation will be severely damaged, affecting the service life of the entire cable, or causing problems such as short circuits, fire and personal injury hazards.
