Copper clad steel stranded wire is made of a certain number of copper-plated single wires twisted by a stranding machine. As the name suggests, copper clad steel is a round steel surface electroplated, so it is a composite cord with a copper layer twisted around the steel round cord. It utilizes the skin effect of low-voltage and high-frequency signals to stroll along the surface in the high-frequency location, so as long as the copper layer thickness reaches a certain range, the signal in a certain frequency range can be guaranteed to be transmitted. Copper plays the role of conducting weak electrical signals, and the steel round wire plays a supporting role. According to the different methods of wrapping copper to steel round wire, it is mainly divided into electroplating, coating, hot casting/immersion and electroforming. This item integrates the toughness and durability of steel with the excellent electric conductivity and deterioration resistance of copper. Compared with copper single cord, it has the advantages of low thickness, high toughness and low cost. It is an updated product of traditional pure copper single wire.
copper clad steel strand is a new composite material processed by evenly electroplating electrolytic copper molecules with a content of 99.9% onto a high-quality low-carbon steel core. This product has the strength and toughness of steel as well as the good conductivity and conductivity of copper. Corrosion resistance. Products are widely used in high-frequency coaxial cables, steel network communications, electrified railways, subway light rails, round wires in power and petrochemical systems, etc. Compared with pure copper, copper-plated steel stranded wire has the advantages of low density, high strength, and low cost. It is an updated product of traditional pure copper stranded wire.
Features of copper clad steel strand:
1. Unique manufacturing process
The material is manufactured using a special process to achieve metallurgical molecular bonding and long service life.
2. Soft structure, large surface volume and good heat dissipation effect.
Using high-temperature welding, there is no residue and no corrosive phenomena. The surface copper layer is thick (conductivity is as high as 30%), has strong corrosion resistance, has a long service life (more than 30 years), and is maintenance-free.
3. Better electrical performance
The skin effect principle, excellent electrical conductivity, and its magnetic permeability properties are conducive to the diffusion and transmission of electromagnetic fields.
4. Safe and reliable
Using special connectors or chemical exothermic welding, the joints are firm and stable.
5. Convenient and fast
Using special heat treatment, it can be made into a soft state, with a large length and a large number of straight-line connection points.
6. Wide usability:
Packed into traps or trays, with few connection points and easy transportation.
l Based on the principle of skin effect, its electrical conductivity is equivalent to that of pure copper wire, and its excellent magnetic conductivity facilitates the transmission and diffusion of lightning present.
l Light weight, high strength and easy to install.
l Adopting special heat treatment, it can be made into a soft state, large length, and a large number of straight-line connection points.
l Made by four-dimensional electroplating barrel plating process, metallurgical melting and casting molecular bonding, lengthy life span.
