One What is a photovoltaic cable? What is the difference between photovoltaic cables and ordinary cables?
Photovoltaic cables, also known as photovoltaic special cables, are mainly used in photovoltaic power stations. They have the advantages of high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV protection, flame retardancy and environmental protection, and long service life. They are mainly used in harsh weather conditions; The commonly used models are PV1-F and H1Z2Z2-K. The characteristics of photovoltaic cables are determined by their special insulation and sheath materials. We call it cross-linked polyethylene. After irradiation with an accelerator, the molecular structure of cable materials will change, providing various aspects of performance.
The difference between photovoltaic cables and ordinary cables
1. Photovoltaic cable:
Conductor: Copper conductor or tinned copper hundred conductor
Insulation: irradiated cross-linked polyolefin insulation
Sheath: Radiation cross-linked polyolefin insulation
2. Ordinary cable:
Conductor: Copper conductor or tinned copper conductor
Insulation: Polyvinyl chloride or cross-linked polyethylene insulation
Sheath: PVC sheath
3. From the above, it can be seen that the conductor used is consistent with the photovoltaic cable.
4. From the above, it can be seen that the insulation and sheath of ordinary cables are different from those of photovoltaic cables.
5. Ordinary cables are only suitable for laying in ordinary environments, while photovoltaic cables can be used for laying in harsh
environments.
