Problems solved by technology

At present, the most used cable in the industry is a kind of flame-retardant polyvinyl chloride material. In order to ensure the flame-retardant performance of the cable, a large amount of halogen-containing fillers are added to the material. Once the cable burns, it will release toxic halogen acid gas, which is harmful to equipment, There is a great safety hazard for personnel

Abstract

The invention discloses a high-temperature-resistant and flame-retardant optical composite communication flexible cable. The optical composite communication flexible cable is characterized by comprising an optical unit, electric units, an inner sheath, a shielding layer and an outer sheath; the multiple electric units are uniformly stranded and wound around the outer side of the optical unit; theinner sheath is arranged on the outer layers of the electric units in an extrusion manner; the shielding layer is arranged on the outer layer of the inner sheath; the outer sheath is arranged on the outer side of the shielding layer in an extrusion manner; each electric unit comprises a feed unit and a signal unit; the inner sheath and the outer sheath adopt a high-flame-retardancy thermoplastic elastomer material of 125 DEG C; and the shielding layer is woven by zinc-plated steel wires, wherein the weaving density is not less than 85%. The temperature resistant level and flame retardancy of the communication flexible cable are improved, so that requirements of different signals and feeding can be satisfied.

Description

technical field [0001] The invention relates to a flexible communication cable, in particular to a high temperature resistant flame retardant optical composite flexible communication cable. Background technique [0002] As operators accelerate the formation and application of 5G communication technology, the communication base stations and data centers used for 5G technology are bound to become denser and more intelligent. The cables and optical cables currently used are laid separately, and the construction is difficult and the wiring is complicated. Compared with laying optical cables and cables separately, the use of a photoelectric composite cable can greatly reduce the construction cost and avoid the waste of resources caused by secondary construction. It is the best choice for low-voltage communication access networks with high integration and resource saving. technology. The photoelectric composite cable has the characteristics of high reliability data transmission,...
