Solar cables are often exposed to sunlight, and solar systems are often used in harsh environments such as high temperatures and ultraviolet radiation.
In Europe, sunny days can lead to solar system site temperatures of up to 100°C. At present, PVC is the various materials we can use, rubber, TPE and high quality cross-link materials, unfortunately the rated temperature is 90°C rubber cables, even PVC cables rated for 70°C are often used outdoors.Currently, the National Golden Sun Project is frequently launched. In order to save costs, many contractors choose ordinary PVC instead of special cables for solar systems. Obviously, using cables instead of photovoltaic cables will greatly affect the service life of the system.
The characteristics of photovoltaic cables are determined by their special insulating materials and sheath materials, which we call cross-linked PE. After being irradiated by a radiation accelerator, the molecular structure of the cable material will change, thereby providing its performance in all aspects.
Resistance to mechanical load.
In fact, during installation and maintenance, cables can be routed on the sharp edges of the roof structure, where the cables must withstand pressure, bending, tension, cross tensile loads and strong impacts. If the cable sheath is not strong enough, the cable insulation layer will be severely damaged, affecting the service life of the entire cable, or causing short circuits, fire and personal injury hazards.
