Degaussing cable for naval vessel

Abstract

The invention discloses a degaussing cable for a naval vessel. The degaussing cable comprises a conductor in the middle of the cable, wherein an aluminum foil mask tape is wrapped outside the conductor; and a low-smoke halogen-free and flame-retardant insulating layer is extruded outside the aluminum foil mask tape. According to the degaussing cable, the degaussing effect can be enhanced effectively, the outer diameter and weight of a product are reduced, and convenience is brought to pavement of the product; the insulating layer is made of a low-smoke halogen-free and flame-retardant crosslinking material, so that the cable carrying capacity, working temperature level and physical and mechanical properties are enhanced greatly, and the running power of the cable is raised remarkably; meanwhile, compared with an ordinary degaussing cable, the cable disclosed by the invention has the advantages that: only a small amount of low-smoke and nontoxic gas is produced during combustion, and the cable belongs to an environmentally-friendly product; and meanwhile, a thin copper soft wire with a high-electric-conductivity clad layer is adopted, so that the corrosion resistance and oxidation resistance of a copper conductor are enhanced.

Description

[0001] technical field [0002] The invention relates to a cable, in particular to a high-efficiency degaussing cable for ships. Background technique [0003] The purpose of ship cable degaussing is to weaken the ship's magnetic field strength as much as possible and improve its distribution characteristics. It is used to improve the ship's magnetic protection capability, defend against underwater magnetic weapons (such as magnetic induction mines) and be found by magnetic detection instruments, and protect ships. Safe navigation. Traditional degaussing cables mostly follow the technology of the former Soviet Union. Its structure is to add insulation to the conductor and then a layer of sheath. The conductor used is soft fine wire copper (used for current transmission), and the insulation and sheath layers are ordinary rubber materials. (used as electrical insulation and protection against external intrusion). However, with the new development of modern ship technology and...

Problems solved by technology

However, with the new development of modern ship technology and the rapid increase of the tonnage of ships, due to the inherent characteristics of the structural materials involved in the original cable, such as the degaussing effect and current carrying capacity, the traditional degaussing cable can no longer be better. To fully meet the new needs of development, mainly in: poor safety due to unsatisfactory degaussing effect, poor environmental protection of cables (smoke and poisonous gas when burning), poor corrosion resistance, large volume, heavy weight, and inconvenient use
