The difference between photovoltaic cables and ordinary cables:
Knowing the difference between solar photovoltaic wires and ordinary wires, you can know why solar photovoltaic wires are more expensive than ordinary wires.
Photovoltaic cable:
Conductor: Copper conductor or tinned copper conductor
Insulation: Irradiated cross-linked polyolefin insulation
Sheath: Irradiation cross-linked polyolefin insulation
Ordinary cable:
Conductor: Copper conductor or tinned copper conductor
Insulation: PVC or XLPE insulation
Sheath: PVC sheath
It can be seen from the above that the conductors used in ordinary cables are the same as those used in photovoltaic cables.
It can be seen from Table 1 that ordinary cable insulation and sheathing are different from photovoltaic cables.
Ordinary cables are only suitable for laying in ordinary environments.
The advantages of photovoltaic power cables: high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV resistance, flame retardant, environmental protection, photovoltaic power cables are mainly used in harsh climates with a service life of more than 25 years.
