Environment-friendly data cable

Abstract

The invention discloses an environment-friendly data cable. The environment-friendly data cable comprises a foam skeleton, a conductor core set, an air bag and an insulation layer. The foam skeleton comprises four raised lines symmetrically arranged and a spinal column, the spinal column is arranged at the center of the environment-friendly data cable, one end of each raised line is connected with the spinal column, the other end of each raised line is connected with a supporting plate, an installation cavity is formed by the raised lines, the spinal column and the insulation layer, the air bag filled with nitrogen is arranged in the installation cavity, and the conductor core set comprises a pair of wires arranged in parallel; a fixing block is arranged on the inner side of the insulation layer to fix the conductor core set; the insulation layer comprises 110 parts of PVC resin, 13-15 parts of dibutyl phthalate, 10-14 parts of trioctyl trimellitate, 15-25 parts of dipentaerythritol hexaacrylate, 6-10 parts of titanium dioxide, 4-5 parts of stearic acid, 3-9 parts of coarse whiting and 0.2-0.3 parts of rose essence. The foam skeleton, the conductor core set, the air bag and the insulation layer which is formed according to a novel formula are adopted, the data cable is lighter, and the adopted materials are more environmentally friendly and free of pollution; the air bag is good in damping effect, convenient to dismount and recover and free of pollution.

Description

technical field [0001] The invention relates to the field of cable production, in particular to an environment-friendly data cable. Background technique [0002] With the rapid development of optical communication technology, optical cables have been widely used in the backbone network and inter-office trunk lines of wired communication networks, and it has become an inevitable trend for optical fibers to enter the access network. However, the cost of laying optical cables is too high, and the cost of joints and terminal optical-electrical conversion is expensive. Therefore, for a long time before the popularization of optical fiber, the subscriber lines of the access network will still be dominated by metal cables. As a kind of metal cable, environmental protection data cable is currently an ideal transmission medium for broadband access network. It has the advantages of low manufacturing cost, simple structure, good expandability and easy network upgrade. It is mainly used...
