     The difference between photovoltaic cables and ordinary cables


     Photovoltaic cables are often exposed to sunlight, and solar systems are often used under harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny days will cause the field temperature of the solar system to reach 100°C. At present, the various materials we can use are PVC, rubber, TPE and high-quality cross-linking materials, but unfortunately, there are rubber cables with a rated temperature of 90°C, and even PVC cables with a rated temperature of 70°C. It is 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 systems, but choose ordinary pvc cables to replace photovoltaic cables. Obviously, this will greatly affect the system. Service life.


     Which wire and cable is better: Choose Suzhou Zhenlei Wire and Cable Co., Ltd., your right choice.


     The characteristics of photovoltaic cables are determined by their special insulating materials and sheath materials for cables, which we call cross-linked PE. After being irradiated by an irradiation accelerator, the molecular structure of the cable material will change, thereby providing all aspects of its performance. .


     In fact, during installation and maintenance, cables can be routed on the sharp edges of the roof structure. At the same time, the cables must withstand pressure, bending, tension, cross tensile loads and strong impacts. If the cable sheath is not strong enough, the cable insulation layer will be severely damaged, which will affect the service life of the entire cable, or cause short-circuit, fire, and personal injury hazards.
