Copper clad steel strand copper clad steel (copper clad steel), that is, copper clad steel core. In fact, the surface of the steel core is uniformly covered with a certain thickness of pure copper metal composite wire. It uses the skin effect principle of low-voltage high-frequency signal to walk along the surface in the high-frequency region. Therefore, as long as the copper layer reaches a certain thickness range, the signal of a certain frequency band can be transmitted. The function of copper is to conduct weak electric signals; The role of steel core is to support. Traditionally, the same clad steel grounding wire generally adopts pure copper wire or galvanized steel, but the conductivity and service life of galvanized steel are far less than that of pure copper wire. However, the disadvantage of pure copper wire is high cost, which is not as affordable as galvanized steel. Therefore, the new copper steel composite conductor can not only carry good conductivity like pure copper wire, but also have rigid strength, and greatly reduce the cost. According to the skin effect, when the copper layer on the surface of the grounding conductor reaches a certain thickness, the current interception of the steel core is small, which can successfully replace the pure copper wire. The product not only has the characteristics of steel strength, toughness, resistance to sudden temperature change and pressure resistance, but also has the advantages of copper corrosion resistance, high conductivity and oxidation resistance. On this basis, it prolongs its service life and reduces the cost. Therefore, this product is an updated product of high-tech products. Compared with the traditional copper strand, this product has the advantages of low density, high strength and low cost, but its work efficiency is quite high. According to the different methods of copper wrapping to the surface of steel core, it is mainly divided into electroplating, coating, hot casting / immersion and electroforming processes. At present, according to the copper-clad steel on the market, the electroplating process is widely used, that is, after the copper is fully dissolved by the electroplating process based on the working principle of electrolytic battery, the current is guided to cover the surface of steel core; What about the coating method? That is to wrap the copper strip around the steel core and use argon arc welding at the wrapped interface; Hot casting / immersion is to heat and melt copper into liquid, cover the surface of steel core, and cool and solidify after a certain time. According to different strength, copper clad steel can be divided into: soft state a, semi-hard state m, hard state HS and superhard state EHS. According to different wire diameters, it can be roughly divided into: (below 0.2) middle line), large line) and thick line (above). Scope of application: this product has been widely used in lightning protection grounding, anti-static grounding, anti-static grounding in petrochemical, railway, electric power, airport, network communication and other places Protective grounding, etc.
