Dual lines will be the choice for overhead high voltage cables

Currently, a new type of cable core - double metal wire is quietly opening the market, cable companies through the development of a variety of bimetallic composite conductor wire, the enterprise to a new stage of development. The bimetallic wire is dominated by copper clad aluminum or copper-clad steel wire, with wire cable to lightweight, high strength, high conductivity, magnetic, stage of development of corrosion-resistant, two-wire replaces the steel core reinforced aluminum conductors become ideal for high voltage overhead cables.

Whether it is through trial and error or just laying experience from abroad or, copper clad aluminum wire and copper clad steel wire bimetallic wire has unique advantages in performance. One has good ductility and workability. Copper Clad Aluminum and Copper Clad Steel can do the same as pure copper wire drawing and the annealing process can be further processed into a deep copper coated wire and silver, tin copper clad steel wire. 

The second is a unique composite property. Copper Clad Aluminum has both conductivity and density of small aluminum composite properties of copper, copper clad steel wire and high-strength will be 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, it has significant economic benefits. Copper clad aluminum wire density of only 36.5% -41.6% copper wire, its length is the same weight, 1 / 2.45-1 / 2.65 times the equivalent diameter of copper lines, the same weight, the same diameter of the copper-clad steel wire tensile strength than pure copper wire more than 1.6-2 times higher. Thus, the wire length or intensity of production of wire and cable 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 that does not pollute the environment. Therefore, copper-clad aluminum and copper-clad steel wire not only have broad market prospects, but the application range is also expanding.

Bimetallic wire belongs to the new generation of products, a wide range of applications, mainly used in the high-frequency signal transmission of electricity, electronics, telecommunications, and other fields of aviation, aerospace, underwater vehicle, electronic components, connectors, computers, instrumentation coil cable, motor transformer winding, television degaussing coil and deflection coil, special high-conductivity wire, radio frequency shielding and other fields.
