The difference between power detection photovoltaic cables and ordinary cables Power detection 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 cause the site temperature of the solar system to reach as high as 100°C. At present, the various materials we can use are PVC, rubber, TPE and high quality cross-link materials, but unfortunately, the rated temperature is 90°C rubber cable, there is even a temperature rating of 70°C's PVC cables are also often used outdoors. At present, the National Golden Sun Project is 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 reduce the cost. Affects the service life of the system. The characteristics of photovoltaic cables are determined by the special insulating material and sheathing material for the cable, which we call cross-linked PE. After irradiation by the radiation accelerator, the molecular structure of the cable material will change, thus provide its performance in all aspects. Resistance to mechanical loads In fact, during installation and maintenance, cables can be routed on sharp edges of roof structures, while cables are subject to pressure, bending, tension, cross tensile loads and strong shocks. If the cable jacket is not strong enough, then The cable insulation will be severely damaged, affecting the service life of the entire cable, or causing problems such as short circuits, fire and personal injury hazards. Radiation cross-linked material with high mechanical strength. The cross-linking process changes the chemical structure of the polymer, the fusible thermoplastic material is converted into a non-fusible elastomeric material, and the cross-linked radiation significantly improves cable insulation thermal, mechanical and chemical properties.
