Problems solved by technology

In addition to excellent physical and mechanical properties and electrical insulation properties, wire and cable sheathing materials also need to have good oil resistance, heat resistance, corrosion resistance and other properties. Traditional cable sheathing materials are increasingly unable to meet harsh working environments.

Abstract

The invention discloses a communication cable. The communication cable comprises a cable core which comprises an H-shaped rubber framework. Wire cores are placed on the left side and the right side of the H-shaped rubber framework respectively. Elastic bars are respectively arranged between each wire core and the front end of the H-shaped rubber framework and between each wire core and the rear end of the H-shaped rubber framework. Each wire core comprises a conductor, and each conductor is sequentially covered with a fluorinated ethylene propylene insulation layer, a tin-coated steel wire braiding shielding layer and an inner sheath. The cable core is sequentially covered with a glass wool rope winding layer, an aluminum-plastic composite film shielding layer, a thermal insulating layer and an outer sheath. According to the communication cable, the cable core is sequentially covered with the glass wool rope winding layer, the aluminum-plastic composite film shielding layer, the thermal insulating layer and the outer sheath, so that the insulating and shielding effect is good, the thermal insulating performance is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a communication cable. Background technique [0002] Communication cables are used more and more widely; communication cables are cables used to transmit telephone, telegraph, fax documents, TV and radio programs, data and other electrical signals. In addition to excellent physical and mechanical properties and electrical insulation properties, wire and cable sheathing materials also need to have good oil resistance, heat resistance, corrosion resistance and other properties. Traditional cable sheathing materials are increasingly unable to meet the harsh working environment. Contents of the invention [0003] The object of the present invention is to provide a communication cable in order to remedy the defects of the prior art. The cable outer sheath material of the present invention improves its oil resistance, heat resistance, corrosion resistance and other properties on the ...
