Preparation method of ultra-flexible high-conductivity stranded conductor

Abstract

The invention discloses a preparation method of an ultra-flexible high-conductivity stranded conductor. Light rare earth metal such as manganese and cerium is added into a high purity copper metal conductor, and when manufacturing alloys by making full use of light rare earth metal such as cerium, the properties of elasticity, toughness and strength of the metal can be greatly improved. The high-conductivity and high-strength copper alloy is obtained by vacuum melting, rapid solidification, hot extrusion, cold pressing, aging and other processes, the tensile strength of the copper alloy is 600N / mm2 which is twice as much as ordinary copper conductors, the conductivity can reach 101.3% (IACS) and the conductivity is more than 20% higher than that of ordinary copper conductors. The strandedconductor made of the copper alloy as the main material through wire drawing, plating, stranding and other processes has good mechanical properties and the strength of the conductor material is greatly increased in comparison with that of ordinary copper conductors so that the processing requirements of cable insulation extrusion, component welding, crimping and the like can be met and the reliability of similar products is improved.

Problems solved by technology

[0002] With the rapid development of national defense science and technology, weapons and equipment have put forward higher requirements for the technical level of special cables, which are characterized by light weight, good flexibility and high reliability. The cable conductor is the most important part of the cable structure. At present, my country's cables The manufacturing process of the conductor cannot meet the research and development needs of special cable products, and the research and development capabilities of high-end conductor materials are far behind the developed countries in Europe and the United States. This patent is jointly developed by multiple cable materials, cable equipment and cable conductor manufacturers. high performance materials

[0003] At present, the minimum single wire diameter of high-performance stranded conductors in my country is 0.051mm, and its material is silver-plated conductors. In cable manufacturing and component processing, affected by the strength of its materials, the conductors have poor roundness, looseness, and strands during processing. Phenomenon, in severe cases, there will be broken strands, which directly affects the subsequent processing quality of the product
