The characteristics of photovoltaic cable are determined by its cable special insulating material and sheath material. We call it cross-linked PE. After irradiation accelerator irradiation, the molecular structure of cable material will change, so as to provide a certain aspect of performance.
The poor UV protection performance of the sheath of the ordinary cable leads to the aging of the outer sheath of the cable, which affects the service life of the cable, and easily leads to cable short circuit, fire alarm or dangerous injury to personnel and other problems. The difference between solar pv cable and ordinary cable is mainly in the insulation and sheath material. photovoltaic cable material is irradiated material. This material is high temperature resistance, cold resistance, oil resistance, anti-aging, anti-ultraviolet, environmental protection.
The difference between ordinary cable and photovoltaic cable:
1. It can be seen from the table that the conductor used for ordinary cables is the same as that for photovoltaic cables.
2. It can be seen from the table that the insulation and sheath of ordinary cable are different from that of light volt cable.
3. Common cables are laid only in common environments.
4. The advantages of photovoltaic power cable: high temperature resistance, cold resistance, oil resistance, acid and alkali salt resistance, UV protection, flame retardant, environmental protection, photovoltaic power cable is mainly used in harsh climates, the service life of more than 25 years.
In fact, during installation and maintenance, cables are subjected to stress, bending, tension, cross-stretching loads, and strong shocks. If the cable sheath is not strong enough, the insulation layer of the cable will be seriously damaged, which will affect the service life of the cable, or lead to problems such as short circuit, fire and human injury.
