Method for manufacturing cable for military industry equipment

Abstract

The invention discloses a method for manufacturing a cable for military industry equipment, comprising the following steps that: (1) an insulation layer is formed by extrusion-molding on a conductor, forming a wire; (2) a plurality of wires are provided, at least one wire among the wires is picked up to be the center wire, other wires are arranged around the center wire; the wires are jointly intertwisted to be a cable core of cable; (3) the cable core of cable is coated with a metallic layer, forming a shielded layer; (4) the shielded layer is covered by paper strips, forming a paper strip layer; (5) a serving is extrusion-molding on the outer part of the paper strip layer by the thermoplast vulcanized rubber. The cable manufactured by the method of the invention has the advantages of fast transmission speed and good screening effect; moreover, because the serving is the low-smoke-halogen-free serving, the cable also has the advantages of environmental protection, anti-ultraviolet performance and cold resistance, and is applied to the military industry equipment which is frequently worked in the field strong and under bad environmental conditions.

Description

technical field [0001] The invention relates to a method for manufacturing power cables, more particularly to a method for manufacturing cables for military equipment. Background technique [0002] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, modern agriculture and scientific research, military equipment or military facilities, space, ocean detection, and have reached a ubiquitous state. With the step-by-step development of social and economic activities from depth to breadth, the varieties of wire and cable are constantly updated and improved, and the production volume continues to increase. For example, the construction of high-intelligence buildings requires computer network cables for hierarchical networking of hundreds or thousands of electronic computers; the establishment of urban public cable TV networks, the universal deposit and withdrawal of all banks in the city and even the ...

AI Technical Summary

Problems solved by technology

In addition, cables for military equipment are usually used in the field, the working environment is very harsh, the temperature changes greatly and they are directly exposed to ultraviolet rays, so the cables are easily aged and damaged, resulting in equipment failure

At the same time, once the outer layer of the existing conventional cable is aged and damaged, halogens are usually produced, causing environmental pollution

At present, the general-purpose cables cannot meet several main conditions of cables for military equipment such as fast transmission speed, good shielding effect, anti-ultraviolet radiation, anti-aging and environmental protection.
