ShandongYanggu Cable FactoryHome Haohui cable teaches you to distinguish between photovoltaic cables and ordinary cables:The thermal market for photovoltaic cables is still in progress. Photovoltaic projects are emerging across the country. There is a great demand for photovoltaic cables. Due to the recent rise in copper and aluminum prices, other raw materials also have an upward trend, and the construction cost of photovoltaic projects has also increased. Today Yanggu HaohuiCableTeach you to distinguish between photovoltaic cable and ordinary cable:


At present, national projects are frequently launched. In order to save costs, many contractors do not choose special cables for solar energy systems, but choose ordinary PVC cables to replace photovoltaic cables. Obviously, this will greatly affect the service life of the system.

Photovoltaic cables are often exposed to sunlight, and solar systems are often used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny days will result in on-site temperatures of up to 100°C for solar systems. At present, we can use a variety of materials such as PVC, rubber, TPE and high-quality cross-link materials, but unfortunately, even rubber cables rated at 90°C or PVC cables rated at 70°C are not competent for the harsh environment encountered by dedicated photovoltaic cables.

What is the difference between photovoltaic cables and ordinary cables?

This type of cable is similar to other cables, including conductor, insulation layer, sheath, necessary filler, etc. The characteristics of photovoltaic cable is determined by its cable special insulation material and sheath material, we call it cross-linked PE, after irradiation accelerator irradiation, the molecular structure of the cable material will change, so as to provide its various aspects of performance.

During installation and maintenance, cables can be routed on the sharp edges of the roof structure, while the cables must withstand pressure, bending, tension, cross-tensile loads and strong impacts. If the strength of the cable sheath is not enough, the cable insulation layer will be seriously damaged, which will affect the service life of the entire cable, or cause problems such as short circuit, fire and personal injury.

Radiation cross-linked materials with high mechanical strength. The cross-link process changes the chemical structure of the polymer, the meltable thermoplastic material is converted to a non-meltable elastomer material, and the cross-link radiation significantly improves the thermal, mechanical and chemical properties of the cable insulation material.

It is necessary and necessary to use special photovoltaic cables for photovoltaic projects.
