Abstract

The invention relates to a copper-clad aluminum-magnesium wire for a communication cable and a manufacturing method thereof. The copper-clad aluminum-magnesium wire for the communication cable comprises an aluminum-magnesium core rod and a copper layer, wherein the copper layer is uniformly and concentrically clad on the surface of the aluminum-magnesium core rod; the copper layer accounts for 18 to 22 percent of the volume of the copper-clad aluminum-magnesium wire for the communication cable. The manufacturing method of the copper-clad aluminum-magnesium wire for the communication cable comprises: 1, melting; 2, cladding and welding; and 3, wire-drawing and annealing. The structural reasonableness, electrical properties, mechanical properties and environmental properties of the copper-clad aluminum-magnesium wire for the communication cable all meet the technical standards for internal wires of the common communication cables, the signal, image and data transmission performance of the copper-clad aluminum-magnesium wire for the communication cable is in complete accordance with high-frequency transmission line skin effect, the copper-clad aluminum-magnesium wire for the communication cable saves copper resource by replacing copper with aluminum, is in accordance with the trend of energy conservation and emission reduction and can greatly reduce the cost of raw materials.

Description

【Technical field】 [0001] The invention relates to a conductor wire and a manufacturing method thereof, in particular to a copper-clad aluminum-magnesium conductor wire for communication cables used in the communication field and a manufacturing method thereof. 【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 i...
