Advantages of PV1-F twin solar cables: 1. Halogen-free: Green environmental protection insulation, sheath and special oxygen barrier materials are used, which not only have good electrical and physical and mechanical properties, but also ensure that the product is halogen-free and solves the problem. The "secondary pollution" formed when it burns avoids the toxic substances produced when the traditional PVC wire burns. 2. Low-smoke and low-toxicity: The use of new special coating materials that are non-polluting to the environment will not produce toxic gases during production, use and combustion, and emit very little acid gas, reducing the damage to personnel and equipment. It is very necessary to use PV1-F twin solar cables in places where people are concentrated.

      The shortcomings of PV1-F twin solar cables and the disadvantages of low-smoke halogen-free cables may be the price and popular use. Although low-smoke and halogen-free cables are environmentally friendly, their raw materials and technical costs are more expensive than ordinary PVC cables. Moreover, because ordinary PVC and polyethylene cables have excellent electrical conductivity, mechanical properties and some other excellent properties, low-smoke and halogen-free cables cannot completely replace ordinary cables, so they are not widely used.
