At present, a new type of core cable, the double wire has quietly opened on the market, Cable Tv Co through the development of a variety of dual metal composite wire, the enterprise is in a new development stage. The bimetallic wire is by copper clad aluminum wire or copper clad steel wire, wire, and cable lightweight, high strength, high conductivity, magnetic resistance, corrosion resistance, the double wire will replace steel core strengthening aluminum strand become an ideal product for high voltage aerial bundled cable.
Whether the results of the test or from the domestic and international experience, the copper clad steel wire and copper clad steel wire, double wire in the performance has a unique advantage. First of all, it has good ductility and operability. Copper-clad aluminum wire, copper-coated copper wire drawing, and annealing treatment do, but also can be further processed into copper enameled wire and silver, tinned copper-clad steel wire.
Two is a unique composite property. The density of the copper clad aluminum wire and conductive copper and aluminum composite material properties, and copper clad steel wire is combined with the conductive copper and steel high strength together, tinned copper clad wire play tin solder and anti vulcanization, silver plated copper clad steel wire to improve conductivity, increase the thermal conductivity of resistance corrosion and oxidation resistance.
Three is with obvious economic benefits. Copper wire density of copper 36.5% - 41.6%. Its length is 1 / 2.45-1/2.65 equal weight and the folds of pure copper, the weight of equal diameter, diameter copper package the tensile strength of the steel wire 1.6-2 times more than pure copper. Therefore, the use of wire length or strength of the wire and cable production will greatly reduce the production cost.
Four is an important social and environmental benefits. Copper-clad aluminum wire and copper-clad steel wire can save large amounts of copper resources that are scarce, reduce the cable weight, easy to transport and network construction, reduce the labor intensity of workers, and coated welding production process does not pollute the environment. Therefore, not only has broad market prospects, copper clad steel wire, and copper clad steel wire but also expanded the scope of application.
The bimetallic wire is the alternative product, a wide range of applications, mainly used in electric power, electronics, communications, and other high-frequency signal transmissions, aerospace, aerospace, water vehicles, electronic components, connectors, computers, instrument coil connecting lines, motors, transformers, electric optic machine degaussing coil and deflection coil, special high conductive chains, RF shielding net, and another battlefield.
