Abstract

The invention discloses a high-tensile-strength aluminum alloy flexible cable and a preparation method thereof, and the preparation method comprises the following steps: S1, preparing a cable core: preparing high-quality raw material ingots such as aluminum, silicon, iron, copper, magnesium, zinc, boron, zirconium, nickel, antimony, lanthanum, lithium and gallium, and forming an alloy aluminum rodthrough smelting, refining and rolling according to the melting point and production requirements of materials, and carrying out multiple wire drawing, wire twisting and annealing according to cableprocess requirements. According to the aluminum alloy flexible cable with high tensile strength and the preparation method thereof, multiple alloy materials are added to assist in improving the cable,and a multiple wire drawing process, a wire twisting process and an armoring process are matched, so that the tensile strength, the conductivity and the heat resistance of the cable are fundamentallyand greatly improved, and the whole cable is softer than a traditional cable; the process is simple and reasonable, the manufacturing cost is low, the machining efficiency is high, and the practicalvalue is high.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to an aluminum alloy flexible cable with high tensile strength and a preparation method thereof. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] In the past, the main component of wires used as transmission lines in my country was copper. However, due to the high price and cost of copper, and the advancement of technology,...
