Copper-clad steel stranded wire is cheap | Xinjiang manufacturers produce copper-clad steel stranded wire with high quality and low price
& Because the copper-clad steel composite material has good electrical conductivity and high mechanical strength, especially the outer coating The copper layer has good corrosion resistance, so it has been widely used in grounding devices. At present, relevant standards in my country stipulate that grounding conductors can be made of copper-clad steel composite materials.
Copper-clad steel strands replace section steel or galvanized angle steel as grounding conductors, and have been increasingly accepted, adopted, valued and popularized by various design institutes and engineering construction units.
Features of Hengtai brand copper-clad steel strand:
Unique manufacturing process: It adopts horizontal continuous casting production process, which is the first in China. The continuous casting process uses electrolytic copper to heat the copper interface to form an alloyed over-plated layer, and the bimetallic interface is completely firmly combined, thereby achieving ductile metallurgical welding between copper and steel and forming a single composite body, which can be like drawing a single Metal can be pulled out at will without any detachment, peeling or cracking.
Better anti-corrosion properties: No residue inside the bimetal, better corrosion resistance. The horizontal continuous casting process uses high-temperature melting, and the residue overflows the copper surface after being calcined, and will not remain in the copper-clad rigid conductor, so there will be no internal corrosion. Using flat steel or building foundation as the grounding body affects the reliability of the grounding device due to poor corrosion resistance. Using galvanized angle steel (round steel) as the grounding body slows down the corrosion of steel, but because zinc is more active than steel, zinc corrodes faster than steel. Since the galvanized layer is in contact with the soil, it is constantly The corrosion is constantly changing, the stability is poor, and the service life is short (generally less than a year). The resistance of the resistor needs to be tested every year, which requires a lot of work. However, copper-clad metal composite materials are used as grounding bodies and lightning protection conductors. Since copper has poor metal activity, it generally does not react with acids, alkalis, and salts. According to the skin effect, when the surface copper layer is larger than the surface, the steel core carries very little current. The strength of the steel is used to send the copper conductor underground, and the surface copper conductor is sent underground. The surface copper layer will not corrode, so the ground rod resistance It will not change over time, can be maintenance-free, and has a service life of up to several years.
Better electrical performance: The surface layer of the copper-clad steel stranded wire is made of oxygen-free copper, which has good electrical conductivity. The inner layer is made of high-quality carbon steel, which conducts electricity based on the skin effect principle and has excellent magnetic conductivity. The resistance is much lower than conventional materials such as steel and galvanized steel. The surface layer is oxygen-free copper.
High adhesion of the copper layer: Because the surface of the copper layer and the steel is a molecular combination, the adhesion is high. When the copper layer is twisted into a strand, the copper layer will not be damaged. Disjoints, peeling, and cracking appear.
Low price: Because its anti-corrosion ability, electrical properties, tensile strength and other properties are completely equivalent to pure copper products, it can directly replace pure copper conductors. Compared with pure copper grounding conductors, it is cheaper and saves a lot of money for engineering projects.
. Easy installation: Horizontal continuous cast copper-clad steel grounding products are welded with exothermic flux. The joints are firm, stable, easy to use, and can meet the low resistance requirements of special occasions.
