The characteristics of the solar cable are determined by its cable special insulation material and sheath material, we call it crosslinked PE, after irradiation accelerator irradiation, the molecular structure of the cable material will change, thereby providing a certain aspect of performance. The advantages of solar cable: high temperature resistance, cold resistance, oil resistance, acid, alkali and salt resistance, UV protection, flame retardant, environmental protection, photovoltaic power cable is mainly used in harsh climate, service life of more than 25 years. In fact, during installation and maintenance, cables are subject to pressure, bending, tension, cross-tensile loads and strong shocks. If the strength of the cable sheath is not enough, the insulation layer of the cable will be seriously damaged, which will affect the service life of the entire cable, or lead to problems such as short circuit, fire and personal injury risk. Therefore, in the long run, the choice of hig…
