Copper coated aluminum-magnesium conductor line for symmetrical cables and manufacture method thereof

Abstract

The invention relates to a copper coated aluminum-magnesium conductor line and a manufacture method thereof. The copper coated aluminum-magnesium conductor line for symmetrical cables comprises an aluminum-magnesium core rod and a copper layer, wherein the copper layer is uniformly and concentrically coated on the surface of the aluminum-magnesium core rod. The manufacture method of the copper coated aluminum-magnesium conductor line for symmetrical cables comprises the following steps: 1. smelting; 2. coating and welding; and 3. wire drawing and annealing. The copper coated aluminum-magnesiumconductor line for symmetrical cables has reasonable structure and can meet the technical standard of a symmetrical cable conductor wire in electrical and mechanical performance, and the transmissionperformance of a signal, an image and data can completely conform to the high-frequency transmission line skin effect; copper sources are saved by replacing copper with aluminum, and the manufactureand application costs of raw materials can be greatly reduced; and the cost of the raw materials is relatively lower.

Description

【Technical field】 [0001] The invention relates to a copper-clad aluminum-magnesium conductor wire and a manufacturing method thereof, in particular to a copper-clad aluminum-magnesium conductor wire of a symmetrical cable used in the communication cable industry and a manufacturing method thereof. 【Background technique】 [0002] Symmetrical cables in the communication cable industry all over the world have long used pure aluminum wires or pure copper wires as conductor wires. Pure aluminum wire (density 2.7), although the cost of raw materials is relatively low, but its electrical conductivity, tensile strength, ductility, and weldability cannot fully meet the functional requirements of symmetrical cables; while pure copper wire has electrical conductivity, Tensile strength, elongation, and weldability can all meet the functional requirements of symmetrical cables, but the cost of raw materials for copper wires (density 8.89) is too high. 【Content of invention】 [0003] I...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problems existing in the prior art that the relative performance of the pure aluminum wire as the conductor wire cannot fully meet the functional requirements of the symmetrical cable, and the raw material cost is too high when the pure copper wire is used as the conductor wire, the present invention provides a symmetrical cable.
