In developed countries, environmentally friendly wires have long become mainstream products of wires, and have been widely used in various industries, especially the automotive and medical industries. XLPE wire is a kind of environmental protection wire.
The environmental protection wire materials include insulation materials, conductor materials and shielding materials. Insulation materials include polyvinyl chloride (PVC), irradiated cross-linked polyvinyl chloride (XL-PVC), irradiated cross-linked polyethylene (XL-PE), halogen-free, silicone, and Teflon and many more. The environmental protection of insulating materials is mainly the RoHS environmental protection directive of the European Union and the environmental protection regulations of children's toys in the EU. It does not contain 6P (Non-6P), which means it does not contain phthalates. The most environmentally friendly is It is low-smoke and halogen-free, completely free of halogen elements, and does not produce harmful halogen gases and corrosive gases. It has a small amount of fever during combustion and does not pollute the soil.
The most common conductor material is copper. Copper has bare copper (called brass, red copper), tin-plated copper, silver-plated copper wire, etc. These categories are still copper in nature, but the surface is plated with other substances to improve oxidation resistance. There are some things that use copper-clad aluminum and copper-clad as conductors, suitable for some large wires and cables and cables with low performance requirements. If the electrical performance requirements are high, copper is the best. The environmental protection of the conductor is mainly required to be free of heavy metals (RoHS).
Now, I believe that everyone has a certain understanding of environmentally friendly wires, that is, halogen-free, non-toxic substances, and meets the environmental protection requirements of Ohm Rohs.
