Problems solved by technology

[0003] Whether the cable is used on the ground or underground, it will be corroded to a certain extent. Due to the poor moisture resistance of the existing cables, the outer layer of the cable is prone to aging in a long-term corrosive environment, which will lead to leakage accidents and ensure the safety of power supply. bring great danger

Abstract

The present invention relates to the technical field of cables, in particular to a cable and a production method thereof. The cable includes a cable core, an insulating layer, a shielding layer, a strengthening layer and an anti-corrosion layer in sequence from the inside to the outside, and the insulating layer is doped with two A rubber layer of silica-wrapped alumina compound; the production method includes: setting an insulating layer outside the cable core; setting a shielding layer outside the insulating layer; setting a strengthening layer outside the shielding layer; setting an anti-corrosion layer outside the strengthening layer. The layers of the cable jointly realize the normal operation of the cable, ensure the quality of the cable, and reduce the probability of damage to the cable and eventual electric leakage accidents.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable and a production method thereof. Background technique [0002] A cable is a basic electrical energy or signal transmission device, usually made of one or several mutually insulated wires and an outer insulating protective layer. It has the characteristics of internal energization and external insulation. It is used in power systems, information transmission, etc. widely. The quality of cables directly affects the quality of projects and the lives of the people. [0003] Whether the cable is used on the ground or underground, it will be corroded to a certain extent. Due to the poor moisture resistance of the existing cables, the outer layer of the cable is prone to aging in a long-term corrosive environment, which will lead to leakage accidents and ensure the safety of power supply. pose great dangers. [0004] Based on this, it is of great significance to provide a cabl...
