PV cable

Photovoltaic cables, also known as photovoltaic special cables, are mainly used in photovoltaic power stations. The common models are PV1-F and H1Z2Z2-K. It is mainly used in harsh climatic conditions.

Advantages of PV cable

It has the advantages of high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV protection, flame retardant and environmental protection, long service life, etc.

PV cable performance

The characteristics of photovoltaic cable are determined by its special insulating material and sheath material. We call it cross-linked PE. After irradiation by the irradiation accelerator, the molecular structure of the cable material will change, thus providing its various performance. In fact, during installation and maintenance, the cable can be routed on the sharp edge of the roof structure, and the cable must withstand pressure, bending, tension, cross tensile load and strong impact. If the strength of the cable sheath is not enough, the cable insulation will be seriously damaged, which will affect the service life of the entire cable, or lead to short circuit, fire and personal injury hazards.

Difference between PV cable and ordinary cable

1. Photovoltaic cable: conductor: copper conductor or tinned copper conductor; Insulation: irradiation cross-linked polyolefin insulation; Sheath: irradiation cross-linked polyolefin insulation. 2. Ordinary cable: conductor: copper conductor or tinned copper conductor; Insulation: PVC or cross-linked polyethylene insulation; Sheath: PVC sheath. 3. It can be seen from the above that the conductors used for ordinary cables are the same as those for photovoltaic cables. 4. It can be seen from the above that the insulation and sheath of ordinary cables are different from photovoltaic cables. 5. Ordinary cables are only suitable for laying in ordinary environment, while photovoltaic cables can be used for laying in harsh environment.
