The tinning copper clad zinc aluminium wire used for the communication cable of the utility model comprises a tin layer, a copper layer, and a zinc aluminium alloy wire, wherein the copper layer is coated on a surface of the zinc aluminium alloy wire, the tin layer is electroplated at an outer layer of the copper layer, the ratio between the sectional area of the copper layer and the sectional area of the zinc aluminium alloy wire is within the range from 1:12 to 1:5, the shapes of cross sections of the tin layer, the copper layer and the zinc aluminium alloy wire are all circular. The tinning copper clad zinc aluminium wire used for the communication cable provided by the utility model not only has good conductivity of the copper, but also has the advantages of low cost, higher elongation, good shielding property and convenient production.
Description
Technical field
The utility model relates to a kind of wire, more particularly, relates to a kind of telecommunication cable tin-coated copper zinc covering aluminum steel.
Background technology
Along with the develop rapidly of China's economic, the demand of various non-ferrous metals is constantly increased.Particularly copper resource, because China is a country that reserves are less, has 50% commercial bronze need to rely on import at present, and therefore the price of copper is constantly soaring in recent years, makes enterprise face the cost pressure day by day strengthening.
It is raw material that the litzendraht wire using in the market all adopts pure copper wire or pure aluminum wire, and (density is about 2.703kg/m to pure aluminum wire
3), although the cost of raw material is relatively low, the mechanical performances such as its tensile strength, ductility, weldability, electric property and environmental performance etc. can not meet the application requirements of telecommunication cable completely; Although and the mechanical performances such as pure copper wire tensile strength, elongation, weldability, electric property and environmental performance etc. all can meet the application requirements of telecommunication cable, (density is about 8.89kg/m to pure copper wire
3) high cost, be not suitable for a large amount of uses, and according to kelvin effect, in the area that the inside of conductor is equal to mutually in same conductor, the electric current that specific surface passes through is much smaller, the performance requirement that therefore wire inner conductor not only can be met to product with external conductor with different metallic combinations is also the scheme of most economical practicality.
