What is the difference between new energy cables and regular cables

On December 11, 2020, photovoltaic cables were frequently exposed to sunlight, and solar systems were often used under harsh environmental conditions such as high temperatures and ultraviolet radiation. In Europe, sunny days can result in on-site temperatures of up to 100 ° C. Currently, various sealing materials we can use include PVC, rubber, TPE, and high-quality cross connect materials, but unfortunately, rubber cables with a rated temperature of 90 ° C, Even PVC cables with a rated temperature of 70 ° C are often used outdoors. Currently, the National Golden Sun Project is frequently launched, and many contractors choose ordinary PVC cables instead of specialized cables for solar systems to save costs. Obviously, this will greatly affect the service life of the system. New energy photovoltaic cables

The characteristics of photovoltaic cables are determined by their specialized insulation and sheath materials, which we call cross-linked PE. After being irradiated by an irradiation accelerator, the molecular structure of the cable material will change, providing various aspects of its performance.

Resistance to mechanical loads

In fact, during installation and maintenance, cables can be routed on sharp edges of the roof structure, and must withstand pressure, bending, tension, cross tensile loads, and strong impacts. If the strength of the cable sheath is insufficient, the insulation layer of the cable will be severely damaged, affecting the entire service life of the cable, or leading to problems such as short circuits, fire, and danger of personal injury.
