Solar cable is a special cable for solar photovoltaic cables, the models are PV1-F, H1Z2Z2-K. What is the difference between solar cables and ordinary cables? Why can’t ordinary wires be applied to energy generation?
Next, let’s compare the conductors, insulation, sheath, and application scenarios of the wires, and analyze the differences between the two.
Through the above introduction, we can find that the conductors of photovoltaic wires and ordinary wires are the same. The difference between them is that the materials of their insulating layers and sheaths are different.
[Irradiation cross-linked polyolefin] Irradiation cross-linked polyolefin has strong environmental adaptability, chemical corrosion resistance, creep resistance and strong high temperature resistance, and the maximum rated temperature can reach 125 °C.
[PVC] has the advantages of stable structure, high chemical resistance, good mechanical strength and insulation properties, but the stability of polyvinyl chloride to light and heat is poor, and the maximum rated temperature is 55°C.
[Cross-linked polyethylen]Its structure is a network structure, which has very excellent heat resistance. Its insulation performance is also higher than that of PE material. The hardness, stiffness, wear resistance and impact resistance of the mechanical properties have all been improved. Chemical resistance, strong acid and alkali resistance, oil resistance. The maximum temperature rating is 90°C.
Due to the particularity of the photovoltaic power generation system, there are special requirements for photovoltaic lines. Photovoltaic lines need to be resistant to weather, high temperature, friction, ultraviolet radiation, ozone, hydrolysis, acid, and salt. Linked polyolefins fit this profile. Polyvinyl chloride (PVC) or cross-linked polyethylene insulation is slightly worse in heat resistance than irradiation cross-linked polyolefin insulation, so ordinary wires cannot be applied to photovoltaic lines.
