Problems solved by technology

[0003] With the emergence of smog in recent years and the deterioration of the air environment, both overhead cables and buried cables have been affected to a certain extent. The harmful substances in the air environment have increased, and the surface of overhead cables in such air for a long time will suffer There are some corroded spots, which greatly shorten the life of the cable. At the same time, the sewage formed by the rainfall flows into the ground, which is also corrosive to the buried cable.

Abstract

The invention relates to a preparation method for a high-strength alloy cable. The preparation method comprises the steps of (1) preparing materials; (2) smelting; (3) refining; (4) performing continuous casing and rolling and draw-benching on an alloy solution; (5) forging; (6) twisting raw materials into a wire core, coating each wire core with an insulating layer, electroplating the outer surface of the insulating layer with a zinc-nickel alloy plating layer, twisting two wire cores into a conductor, and taking at least one conductor as a cable core; (7) performing ion treatment on the cable core; (8) performing electroplating; (9) coating the cable core with a shielding layer and an outer sheath in sequence, reserving gaps between the cable core, the shielding layer and the outer sheath separately, and coating the shielding layer with a zinc-plated steel wire armor layer; and performing vacuuming on the reserved spaces between the cable core, the shielding layer and the outer sheath; and (10) covering the outer surface of the outer sheath with a china protection layer. The overall corrosion resistance and structural strength of the high-strength alloy cable are both greatly improved, so that the normal operation of the high-strength alloy cable in various working environments is ensured; and in addition, the service life of the high-strength alloy cable is prolonged.

Description

technical field [0001] The invention relates to a preparation method of a high-strength alloy cable, which belongs to the technical field of power cables. Background technique [0002] At present, with the development of science and technology, both industry and human daily life are developing in the direction of electrification, and the status of cables in the field of industry and power is gradually increasing. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, aluminum alloy cables and so on. The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated Covering layer, used to connect circuits, appliances, etc. ...
