Differences between photovoltaic cable wires and common cable wires

When it comes to photovoltaic (PV), everyone will think of solar energy. Nowadays, new energy has gradually penetrated into people's daily life. As a new renewable energy technology, the development and market of photovoltaic has been paid more and more attention. The application of photovoltaic cable needs a lot. However, do you know the difference between photovoltaic cable and general cable? Photovoltaic cables are often exposed to sunlight, and solar management systems are exposed to high temperature ultraviolet radiation when used in harsh natural conditions. In the European region, the favorable terrain of sunny days can make the temperature of the solar energy management system reach 100 ° C. Today, we can choose from a variety of materials such as PVC, vulcanized rubber, TPE and high-quality cross-connect materials. But unfortunately, even the vulcanized rubber cable with a temperature of 90 ° C and the polyvinyl chloride (PVC) cable with a temperature of 70 ° C are often used outdoors. Today, when the Golden Sun Project has been carried out many times in China, many contractors do not choose the special cable for solar energy management system in order to save costs better. Just choose ordinary PVC cable instead of photovoltaic cable, which will undoubtedly greatly endanger the application life of the system. PV cable is characterized by the selection of its cable-specific type of insulation material and sheath material, which we call cross-linked polyethylene. After irradiation by the irradiation network accelerator, the molecular formula of the cable material will be modified, and then the functions of its layers will be provided. Protection against mechanical equipment loads. In fact, during installation and maintenance, cables can be routed around sharp corners of the roof structure, and they must withstand forces, bending, bracing, cross-pull, and extreme impact. If the compressive strength of the cable sheath is not enough, the cable sheath will be seriously damaged, which will endanger the service life of the whole cable, and may cause short circuit failure, fire accident, employee injury and other phenomena.
