How much knowledge do you know about solar photovoltaic wires?

Could you tell me how much knowledge do you know about solar photovoltaic wires?

Photovoltaic cables are constantly exposed to sunlight, and solar systems are often exposed to harsh environmental conditions, such as high temperatures and UV radiation. In Europe, sunny days will result in on-site temperatures of up to 100°C for solar systems.

Currently we have a variety of materials available including PVC, rubber, TPE and high quality cross-connect materials, but unfortunately are rated at 90°C Even the PVC cables with a rated temperature of 70°C are 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 cables. The pvc cable to replace the photovoltaic cable, obviously, this will greatly affect the service life of the system.

The characteristics of photovoltaic cables are determined by the special insulating materials and sheathing 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 its performance in all aspects. 

Resistance to mechanical loads

In fact, during installation and maintenance, the cables can be routed on the sharp edges of the roof structure, while the cables are subjected to pressure, bending, tension, cross tensile loads and strong shocks. If the cable jacket is not strong enough, 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.
