Birnetallic Wire Will Become the Ideal Product for Overhead High-voltage Cable

Number of visits: Date:3/23/2015 10:16:42

Currently, a new type of cable core - bimetallic wire quietly opening the market, cable companies has went through the development of a variety of bimetallic composite conductor wire, pushing the enterprise to a new stage of development. Bimetallic wire is dominated by copper clad aluminum or copper clad steel wire, with the wires and cables goes to development stage of lightweight, high strength, high conductivity, magnetic, and corrosion-resistant, and it will  replace aluminum wire becoming ideal product for overhead high voltage cables.

Whether it is through trial and error or just laying experience from abroad or, copper clad aluminum and copper-clad steel wire and other bimetallic wire has unique advantages in performance. One has good ductility and machinability. Copper Clad Aluminum and Copper Clad Steel can do the same as copper wire drawing and annealing can be further processed into a deep enameled copper clad and silver, tin copper clad steel wire. The second is a unique combination of properties. Copper Clad Aluminum along with conductivity and density of small aluminum composite properties of copper, copper clad steel wire and high strength then the conductivity of copper and steel together, tinned copper clad steel wire played a tin can weldability and anti-curing properties, silver-plated copper clad steel wire is to improve the electrical conductivity, thermal conductivity, enhanced corrosion resistance, oxidation resistance. Third, have significant economic benefits. Copper clad aluminum wire density of only 36.5% -41.6% pure copper wire, its length is the same weight, 1 / 2.45-1 / 2.65 times the equivalent diameter of the copper wire, the same weight, the same diameter of the copper-clad steel wire High tensile strength than pure copper wire more than 1.6-2 times. Thus, the use of wire length or strength wire and cable production will greatly reduce production costs. Fourth, significant social and environmental benefits. Copper Clad Aluminum and Copper Clad Steel can save a lot of scarce copper resources, reduce cable weight, easy to transport and network construction, reduce labor intensity, and coated welding production process does not pollute the environment. Therefore, copper clad aluminum and copper-clad steel wire not only has broad market prospects, the application range is also expanding.

Bimetallic wire belongs to replacement products and has wide range of applications, mainly used in high-frequency signal transmission of electricity, electronics, telecommunications and other fields of aviation, aerospace, underwater vehicle, connectors electronic components, computers, instrumentation cable coil motor transformer windings, TV degaussing coils and deflection coil, special high conductivity wire, radio frequency shielding net and other fields.
