Description

Copper Clad Steel Stranded Wires With the constant popularity of electronic communication and large-scale power plants, EHV power transmission lines and high-rise buildings continue to emerge, the security protection of life and death plays an extremely important role, and its reliability has been more and more attention. With steel or construction materials as a basic grounding, corrosion-resistant because of the effect of bad reasons, the impact of the grounding device reliability. The use of galvanized angle steel (bar) to do grounding, although slowed down the corrosion of steel, but zinc and lively than steel, zinc corrosion rate faster than steel. According to skin effect, when the surface of copper layer is greater than 0.*5mm, the steel contains a small stream, using the strength of steel to the copper conductor will be underground, the surface of copper conductor to the ground, the surface layer of copper corrosion will not occur, thus grounding rod resistance will not happen with the passage of time changes, can achieve maintenance-free, life-expectancy of up to *0 years. The Characteristics of Copper Clad Steel: *-A unique manufacturing process: the use of horizontal continuous casting production process, the process for domestic initiatives. Continuous casting process will be used in electrolytic copper are heated to ***0 degree C when combined with copper alloy surface formed over coating, bi-metallic interface completely solid combination of copper and steel in order to achieve ductile metallurgical weld between, as a single complex may be as Drawing a single metal, like any drawing, does not appear out of touch, Erythroculter skin, cracking phenomenon. *-Anti-corrosion properties better: bimetals internal no residue, better corrosion resistance. Horizontal continuous casting process with high temperature melting, residues were calcined copper surface after the spill, there would be no residue in the copper clad lead just inside the body, and therefore will not be any internal corrosion. *-Better electrical performance: for the oxygen-free copper surface, good electrical conductivity properties, the inner layer for high-quality carbon steel, skin effect of the principle of electrical conductivity, magnetic properties of merit. Resistivity much lower than steel, galvanized steel and other conventional materials. Surface for the oxygen-free copper. *-High copper layer adhesion: are because copper layer and steel surface are a combination of elements, so bonding and high twist at a time when synthetic strander, copper layer will not be to destruction, not out of line, Erythroculter skin, cracking phenomenon. *-Low prices: because of its anti-corrosion, electrical properties, tensile strength and other properties of exactly the same as pure copper products, so can directly substitute for copper conductors. Compared to pure copper earthing conductor, low price, the project can save a lot of money. *-Install convenient, pleasing in appearance: The company produces the level of even the bronze-clad steel grounding Products using our patented products "heat flux" to connect, connections solid, stable, well and easy to use. To meet the low-resistance requirements for special occasions. Product surface treatment bright and beautiful and pretty. The Technical Parameters: *-Copper layer average thickness (conventional) >= 0.*5mm; *-Tensile strength >= **0N/mm 2 *-Flatness error <= 1mm *-Copper layer plasticity: grounding rods bent *0, the angle with no cracks. Applications: This product applied to the general environment, and special environment (humidity, salinity, acid soil and chemical corrosion medium), petrochemical, power, communications, rail transport, post and telecommunications, such as lightning protection grounding requirements of the field of higher.
