The most common conductor material is copper. We all know that copper has bare copper (called brass, red copper), tinned copper, silver-plated copper etc. For instance, the speaker wire we manufactured mainly use bare copper as it’s conductor; High temperature wires mainly use Tinned copper or Silver plated copper as it’s conductor. Compared with copper conductor, aluminum conductor has the advantages of light weight and low price. It also has good electrical conductivity, but there is a certain resistance loss relative to copper.Therefore, aluminum conductors are commonly used in low voltage and long distance transmission lines.

If electrical performance requirements are high, naturally copper is the best choice. The environmental protection of conductors is mainly required to contain no harmful elements (RoHS). The material includes insulation material, conductor material and shielding material. Insulation such as polyvinyl chloride (PVC), irradiated cross-linked polyvinyl chloride (XL-PVC), irradiated cross-linked polyethylene (XL-PE), low smoke Halogen free, silicone rubber, Teflon and so on. The environmental protection of insulation materials is currently mainly the Non-6P (non-6P) required by the European Union's RoHS environmental protection directive and the European Union's environmental regulations on children's toys, that is, no phthalates. And now the most environmentally friendly is low-smoke halogen-free, completely free of halogen elements.
