Aluminum alloy material for cables

Abstract

The invention relates to an aluminum alloy material for cables. The aluminum alloy material for cables comprises the following elements in parts by weight: Cu: 1-3 parts, Fe: 0.8-2 parts, B: 0.6-1.8 parts, Mg: 1. 2-2.5 parts, Zn: 5-10 parts, Ag: 0.1-0.5 part, the balance being Al and unavoidable impurities, aluminum ingots and an alloy comprising the corresponding composition in ratio are added to a shaft furnace, and the alloy elements are added in a form of an intermediate alloy and are stirred, refined, deslagged and extruded into bars, and finally the bars are quenched by cold water. The aluminum alloy material provided by the invention has the beneficial effects that appropriate amounts of Ag and iron are added to the aluminum alloy, so that the conductor characteristic of the material is improved, and the resistance is reduced; meanwhile, the tensile strength of the material is enhanced, and the diameter of a steel core can be reduced in the manufacturing process of overhead lines, so that the mass of the overhead lines is reduced, the energy is saved, and the material is easy to popularize.

Description

technical field [0001] The invention relates to a cable aluminum alloy material. Background technique [0002] Wires and cables refer to wires used for power, communication and related transmission purposes. They are indispensable basic equipment for transmitting electric energy, transmitting information, performing electromagnetic conversion, and manufacturing various motors, electrical appliances, and instruments. Usually, products with few cores, small diameter and simple structure are called wires, insulated wires are also called cloth wires, those without insulation are called bare wires, and others are called cables. The main structure of the wire is "conductor + insulation", and the main structure of the cable is "conductor + insulation + sheath". The conductors are generally made of copper or aluminum, and the insulation and sheath are generally made of rubber and plastic. Wires and cables are divided into five categories according to their usage: power cables, wir...

AI Technical Summary

Problems solved by technology

[0003] As a commonly used overhead line, aluminum-clad steel wire is widely used in power transmission. The core of aluminum-clad steel wire is steel wire, and the outer layer is aluminum wire, which can ensure its power transmission efficiency and its tensile strength. The current world Resources are increasingly tight, and the materials used for wires are also extremely strict. Traditional steel-clad aluminum wires have gradually failed to meet the requirements of modern economical production. Therefore, an improved technology is urgently needed to solve the above technical defects.
