Copper-plated steel strand
Application scope and function of copper-plated steel strand:
General ground and horizontal grounding body with high requirements for working environment, such as humidity, saline, acidic soil, and special environment where chemically corrosive media are produced.
1. Better anti-corrosion characteristics: no residue inside the bimetal, better corrosion resistance.Electroformed copper-clad steel strand is a combination of molecules, so there is no corrosion inside.
2. Better electrical performance: the surface layer is oxygen-free copper, with good electrical conductivity, the inner layer is made of high-quality carbon steel, and the skin effect principle is conductive and has excellent magnetic permeability.The resistance is much lower than conventional materials such as steel and galvanized steel.
3. The copper layer has high adhesion: because the copper layer and the surface of the steel are a combination of molecules, the adhesion is high. When the stranded wire is twisted, the copper layer will not be damaged, and there will be no disconnection, Peeling and cracking.
4, low price: because of its anti-corrosion ability, electrical performance, tensile strength and other properties are completely equivalent to pure copper products, it can directly replace pure copper conductors.Compared with pure copper ground conductors, the price is low, which can save a lot of money for engineering projects.
5. Convenient installation and beautiful appearance: using exothermic flux to connect with copper-clad steel ground electrode, the joint is firm, stable and easy to use.Can meet the requirements of low resistance in special occasions.The surface of the product is brightly treated, beautiful and beautiful.
