Description

Anti-interference halogen-free low-smoke flame-retardant shielding computer communication cable

Technical Field

The utility model relates to the technical field of cables, especially, relate to an anti-interference does not have steamed low fire-retardant shielding computer communication cable of cigarette.

Background

A cable is a cable that transmits telephone, telegraph, facsimile documents, television and radio programs, data and other electrical signals. Is formed by twisting more than one pair of mutually insulated wires. Compared with an overhead open wire, the communication cable has the advantages of large communication capacity, high transmission stability, good confidentiality, less influence of natural conditions and external interference and the like.

Although communication cable is by extensive use, nevertheless pluck under some special environment, perhaps the abominable place of environment, the unable normal use of traditional cable, for this reason, the utility model discloses an anti-interference does not have steamed low fire-retardant shielding computer communication cable of cigarette compares in prior art, the utility model discloses a waterproof nature is better, and is difficult for burning.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide an anti-interference there is not steamed low fire-retardant shielding computer communication cable of cigarette, solve above-mentioned problem.

The utility model discloses a realize through following technical scheme: an anti-interference halogen-free low-smoke flame-retardant shielding computer communication cable comprises a sheath, a total shielding layer, a wrapping layer and a plurality of twisted pairs, wherein the wrapping layer is coated outside the twisted pairs, the total shielding layer is coated outside the wrapping layer, and the sheath is coated outside the total shielding layer; the twisted pair comprises a branch shielding layer, an insulating layer and a conductor, wherein the insulating layer is extruded outside the conductor, the branch shielding layer is arranged outside the insulating layer, and a plurality of strip-shaped bulges which are arranged at equal angles are arranged on the outer surface of the sheath.

Preferably, the total shielding layer and the sub-shielding layers are all tinned copper wires woven to form a mesh-shaped woven layer, and the weaving density of the mesh-shaped woven layer is greater than 85%.

Preferably, the insulating layer is a cross-linked polyethylene material.

Preferably, the jacket is made of low-smoke halogen-free polyolefin material.

Preferably, a waterproof tape is further wrapped outside the wrapping layer to form a waterproof layer.

The utility model discloses an anti-interference steamed low fire-retardant shielding computer communication cable of cigarette that lacks, compare with prior art:

the utility model discloses a shielding layer can shield external disturbance, is the polyester area around the material of covering, can effectual insulation, and the water-blocking tape has waterproof function, the utility model discloses can use under adjusting abominable condition, wherein the bellied material of strip is wear-resisting material, can protect the sheath.
