Hebei Cheng'an copper-clad steel grounding wire product definition
Copper clad steel (copper-clad steel) is also a copper-clad steel core. In fact, the surface of the steel core is evenly covered with a certain thickness of pure copper metal composite wire. It uses the skin effect principle of low-voltage high-frequency signals 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 segment can ensure the transmission. The role of copper is to conduct weak electrical signals; the role of the steel core is to support. Traditionally, the same-clad steel grounding wire is generally made of pure copper wire or galvanized steel, but the conductive and service life of galvanized steel is far less than that of pure copper wire. However, the disadvantage of pure copper wire is that it is expensive, and there is no galvanized steel. Therefore, the new copper-steel composite conductor can carry good electrical conductivity like pure copper wire, and at the same time has both rigid strength and greatly reduced cost. According to the skin effect, when the copper layer on the surface of the grounding conductor reaches a certain thickness, the steel core has a small interception, which can successfully replace the pure copper wire. The strength, toughness, sudden temperature difference, pressure resistance, etc. of the steel are included in the product. It also has the advantages of corrosion resistance, high electrical conductivity and oxidation resistance of copper. On this basis, it prolongs its service life and reduces the cost. Therefore, the product is a new generation of high-tech products. Compared with the traditional copper strand, the product has the advantages of low density, high strength and low cost, but its working efficiency is equivalent. According to the method of copper wrapping to the surface of the steel core, it is mainly divided into electroplating, coating, hot casting and electroforming. At present, according to the copper clad steel on the market, the electroplating process is widely used. After the copper is fully dissolved by the electroplating process using the working principle of the electrolysis cell, the current is guided to cover the surface of the steel core; The copper strip is wrapped around the steel core, and the argon arc welding is used at the interface of the package; the hot casting immersion is to melt the copper into a liquid, cover the surface of the steel core, and cool and solidify after a certain period of time. According to the difference of strength, copper clad steel can be divided into: soft A, semi-hard M, hard HS, super hard EHS according to the wire diameter, roughly divided into: microwire (0.2 or less), midline (0.2~) 0.6),
Large line (0.6~1.6), thick line (1.6 or above)
Scope of application: This product has been widely used in lightning protection grounding, anti-static grounding, protection grounding, etc. in petrochemical, railway, electric power, airport, network communication and other places.
