Copper-plated flat steel is made of electrolytic copper as raw material and adopts low carbon steel electroplating technology. The thickness of the copper plating layer at each point is greater than 0.254mm. It is used for equipment to connect to ground down conductors and ground grids to connect horizontally to the ground body. The wiring is neat and convenient. Copper-plated flat steel is a new type of bimetallic composite material with high strength, high elasticity, high thermal resistance and high magnetic permeability. specialty. Copper has good electrical conductivity and excellent corrosion resistance.
There are generally three technologies for copper-plated flat steel products on the market, one is electroplating, one is copper plating, and the other is horizontal continuous casting. The cost of horizontal continuous casting is generally high, and this technology is not suitable for the access point of copper-plated steel products. High-purity electrolytic copper is completely attached to the steel core through the principle of electrolysis, forming an alloyed molecular structure on the copper-steel bonding surface, fully combining with the bimetallic interface, achieving a ductile metallurgical connection between copper and steel, and forming the whole.
The manufacturing technology characteristics of copper-plated flat steel can achieve a high degree of integration of steel. The surface copper layer consists of electrolytic copper. It not only overcomes the primary cell reaction defects during the production process of the casing method, but also solves the insufficient purity of the copper layer during the hot dip continuous casting process and the defects of the positive and negative sides of the surface copper layer. The material with excellent corrosion resistance of copper-plated flat steel shows that the thickness of the copper layer is large, and the average thickness is greater than 0.25mm.
Therefore, it has strong corrosion resistance and has a service life of more than 50 years. Because the surface copper layer is composed of electrolytic copper molecules, its own resistance is much lower than traditional materials. This product is suitable for soil conditions of varying moisture levels. Compared with the traditional copper ground connection method, the cost is greatly reduced, and it is suitable for lightning protection of railways, power stations, power stations, etc.
Copper-plated flat steel is a new type of horizontal access electrode, which is made of steel flat steel through electroplating or continuous casting technology. Made of special steel core surface coated with copper. It has the same conductivity as copper tape but costs much less than pure copper. Its corrosion resistance is much better than galvanized flat steel. It has good electrical conductivity, low resistance, good corrosion resistance, and is easy to transport and construct. It is an alternative to traditional ground connection materials such as round steel, angle steel, and galvanized flat steel.
Cold-rolled flat steel is used for copper-plated flat steel, and the outer mirror thickness is 0.254mm pure copper. The copper layer is strong and has strong corrosion resistance. The bending angle is 180°. It is suitable for working access points, lightning protection access points and anti-static access points in humid, saline-alkali, acidic soils, general environments where chemical corrosive media are generated, and special environments. Copper-plated flat steel has excellent mechanical properties and corrosion resistance, and is recommended for use in places with severe corrosion.
