The difference between photovoltaic cable and ordinary cable

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

But sorry, additional rubber cable temperature of 90 ° C, and even additional temperature of 70 ° C PVC cable is often used in the outdoor, and now the country's gold sun engineering the horse again and again, there are many contractors in order to save money, not to choose cable specially used for solar system, but the general PVC cable instead of a solar pv cable, Obviously, this will greatly affect the service life of the system.

2230a910dd8685f57c8d11d216581f3aThe 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 cable material will change, and then supply its functions.

Resistance to mechanical load, in fact, during equipment and maintenance, the cable can be routed on the sharp edge of the roof structure, together with the cable must withstand pressure, bending, tension, cross-stretching load and strong impact. Assuming that the cable sheath strength is not available, the cable insulation layer will be severely damaged, and then affect the service life of the whole cable, may lead to short circuit, fire and personnel hazards and other problems.
