At present, a new type of cable core-Bimetal line is quietly open the market, cable enterprises through the development of a variety of bimetal wire composite wire, the enterprise to a new stage of development.

Double metal wire is composed of copper clad aluminum wire or copper clad steel wire, along with the wire and cable to light, high-strength, high conductivity, magnetic, corrosion-resistant development stage, bimetal wire will replace the steel core reinforced aluminum stranded wire as an ideal product for overhead high-voltage cable.

Whether through repeated tests, or from the domestic and international laying experience, copper clad aluminum wire and copper clad steel wire and other bimetal lines have unique advantages in performance. One is a good ductility and machinable.

Copper clad aluminum wire and copper clad steel wire can be like pure copper wire to do drawing and annealing treatment, but also further processing into copper-clad enameled wire and silver-plated, tinned copper clad steel wire. The second is a unique composite performance.

Copper clad aluminum wire also has a composite property of copper conductivity and small aluminum density, copper clad steel wire will be copper conductivity and high strength of the iron combined, tinned copper clad steel wire to play the solderability and vulcanization of tin, silver plated copper clad steel wire to improve the conductivity, thermal conductivity, enhanced corrosion resistance, oxidation resistance. The third is to have obvious economic benefits. Copper clad aluminum wire density is only 36.5%-41.6% of pure copper wire, its length is the same weight, the same diameter of the pure copper wire 1/2.45-1/2.65 times, the same weight, the same diameter copper clad steel wire tensile strength of 1.6-twice times higher than pure copper.

Therefore, the use of wire length or strength to produce wire and cable will greatly reduce production costs. Four are remarkable social and environmental benefits. Copper clad aluminum wire and copper clad steel wire can save a large amount of scarce copper resources, reduce cable weight, facilitate transportation and network construction, reduce labor intensity, and the process of coating welding technology does not pollute the environment.

Therefore, the copper clad aluminum wire and the copper clad steel wire not only has the broad market prospect, the application scope also is expanding unceasingly. The bimetal line belongs to the replacement product, wide range of applications, mainly used in electric power, electronics, communications and other high-frequency signal transmission areas and aviation, aerospace, underwater vehicles, electronic components connectors, computers, instrumentation coil connection line, motor, transformer winding, TV degaussing coil and deflection yoke, special high conductivity stranded wire, RF Shielding Network and other fields.
