Problems solved by technology

[0002] At present, with the development of science and technology, industry, coal mines and maritime navigation are also developing rapidly. Cables, as a necessity for connecting equipment, are also developing rapidly. Traditional cables can only play a conductive role, which is far from satisfying. The ever-growing needs require cables to have the advantages of degaussing, fire resistance and flame retardancy in some fields

Abstract

The invention discloses a degaussing, inflaming retarding and shielding cable. The cable is composed of conductors, an insulation layer, an inorganic fireproof belt and an outer sheath. The conductors are separated and surrounded by PP plastic connecting rods. Four reinforcing cores are arranged in the gaps between the insulation layer and the PP plastic connecting rods. The insulation layer is wrapped by a shielding layer. The shielding layer is formed by tightly extruding the outer sheath, the inorganic fireproof belt and a ceramic fluorine insulation wrapping layer from outside to inside. In conclusion, the low smoke zero halogen fireproof torque-resistant industrial cable has the advantages of being good in high temperature resistance, degaussing performance, bending resistance, torque resistance and fireproof performance and the like.

Description

technical field [0001] The invention relates to cables, in particular to a degaussing and flame-retardant shielded cable. Background technique [0002] At present, with the development of science and technology, industry, coal mines and maritime navigation are also developing rapidly. Cables, as a necessity for connecting equipment, are also developing rapidly. Traditionally, cables can only conduct electricity, which is far from satisfying. The ever-growing needs require cables to have the advantages of degaussing, fire resistance and flame retardancy in some fields. Contents of the invention [0003] In order to overcome the above disadvantages, the object of the present invention is to provide a low-smoke, halogen-free, fire-resistant, fire-resistant, torsion-resistant industrial cable. [0004] The scheme of the present invention is as follows: a degaussing and flame-retardant shielded cable, which is composed of conductors, insulating layers, inorganic fire-resistant...
