PV cables are different

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

But unfortunately, the rubber cable with an additional temperature of 90 ° C, and even the PVC cable with an additional temperature of 70 ° C are often used outdoors, and now the national golden sun project has been repeatedly launched, and there are many contractors in order to save costs, not to choose solar system special cables, but to choose general PVC cables instead of photovoltaic cables, obviously, this will greatly affect the service life of the system.

The characteristics of photovoltaic cable are selected by its cable special insulation material and sheath material, we call it cross-linked PE, through irradiation accelerator irradiation, the molecular structure of the cable material will change, and then supply its function.

Resistant to mechanical loads, in fact, during equipment and maintenance, cables can be routed on the sharp edges of the roof structure, together with pressure, bending, tension, cross-tensile loads and strong impacts. Assuming that the strength of the cable sheath is not enough, the cable insulation will be severely damaged, which will then affect the service life of the entire cable, which may lead to problems such as short circuit, fire and personal hazard hazards.
