Photovoltaic cables are often exposed to sunlight, and solar systems are often used in harsh environmental conditions such as high temperatures and ultraviolet radiation. In Europe, the on-site temperature of solar systems is as high as 100°C on sunny days. At present, we can use a variety of materials PVC, rubber, TPE, etc. Unfortunately, the rated temperature is 90°C rubber cable, even if the rated temperature is 70°C PVC cable is often used outdoors. At present, national Golden Sun projects are frequently launched. In order to save costs, many contractors do not choose special cables for solar systems, but use ordinary PVC cables instead. Obviously, replacing photovoltaic cables with cables will greatly affect the service life of the system.

The characteristics of photovoltaic cable are determined by its cable special insulation material and sheath material, we call it crosslinked PE, irradiation accelerator irradiation, the molecular structure of the cable material will change, thereby providing all aspects of its performance.

The difference between photovoltaic cable and ordinary cable

1, photovoltaic cable:

Conductor: Copper conductor or tinned copper hundred conductor

Insulation: Irradiation crosslinking polyolefin insulation

Sheath: irradiated cross-linked polyolefin insulation

2, ordinary cable:

Conductor: Copper conductor or tinned copper conductor

Insulation: PVC or crosslinked polyethylene insulation

Sheath: polyvinyl chloride sheath

3, it can be seen from the above that the conductor used in the ordinary cable is consistent with the photovoltaic cable, and the insulation and sheath of the ordinary cable are different from the photovoltaic cable.

(4) Ordinary cables are only suitable for laying in ordinary environments, but photovoltaic cables can be used for laying in harsh environments.
