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.

Abstract

The invention discloses a cable aluminum alloy material, comprising the following elements in parts by weight: 1-3 parts of Cu, 0.8-2 parts of Fe, 0.6-1.8 parts of Cr, 1.2-2.5 parts of Mg, 5-10 parts of Zn, 0.1-0.5 part of Ag, 0.8-1.5 parts of Ni, and the balance of Al and inevitable impurities. The invention has the following beneficial effects: proper amounts of Ag and Fe are added into the aluminum alloy, so that the electrical conductivity of materials is improved, the resistance is reduced, meanwhile, the tension strength of the materials is enhanced, the diameter of a steel core can be reduced in a manufacturing process of an overhead line, consequently, the mass of the overhead line is reduced, and the energy is saved; Ni is added, so that the resistance to corrosion of the alloy is improved greatly, and the alloy 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...
