Abstract

The invention relates to a method for producing a copper-coated aluminum magnesium conductor wire for a communication cable, which comprises an aluminum magnesium core bar and a copper layer. The aluminum magnesium core bar is coated with the copper layer evenly and concentrically, and the volume of the copper layer accounts for 18%-22% of that of the copper-coated aluminum magnesium conductor wire for the communication cable. Method for producing the copper-coated aluminum magnesium conductor wire for the communication cable comprises the steps of melting; coating and welding; and drawing and annealing. The copper-coated aluminum magnesium conductor wire for the communication cable is reasonable in structure, electric properties, mechanical properties and environmental performances can meet the technical specifications of conductors used for communication cables, transmission performances of signals, images and data are completely in conformity with the high-frequency transmission line skin effect, a copper resource is saved by using aluminum instead of copper, energy is saved, emission is reduced, and the cost of raw materials is greatly reduced.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a conductor wire, in particular to a method for manufacturing a copper-clad aluminum-magnesium conductor wire for communication cables used in the communication field. 【Background technique】 [0002] In the field of communication, communication cables usually use pure aluminum wire or pure copper wire as the inner conductor. Pure aluminum wire (density is about 2.703 kg / m3), although the cost of raw materials is relatively low, but its tensile strength, ductility, weldability and other mechanical properties, electrical properties and environmental performance cannot fully meet the needs of communication cables. application requirements; while pure copper wires can meet the application requirements of communication cables with tensile strength, elongation, weldability and other mechanical properties, electrical properties and environmental performance, but pure copper wires (density is about 8.89 kg / ...
