Thickened red copper has high electrical conductivity, and red copper is used as raw material, which has strong electrical conductivity, high electrical conductivity, low heat generation, strong current carrying capacity and safer; the surface layer is pickled for corrosion resistance and durable, and the surface layer of the product is treated by pickling process, smooth and free of burrs , not easy to oxidize, can prolong the service life; body die-casting refuses welding, real materials are integrally formed, no welding, avoid spark splash caused by excessive current, high temperature resistance, reliable wiring; fine material is not copper-plated, installation wiring is firm, The conduction is stable and smooth, one-time connection is maintenance-free, and the surface of the real material is not galvanized.
