Description

The self-bearing type optoelectronic composite cable
Technical field
The utility model belongs to electric power, communications optical cable technical field, especially a kind of composite rope of self-bearing type.
Background technology
In the prior art, normally laid electric pole in advance, will support wire rope then and set up,, and adopted hook, wire clamp or ply-yarn drill that optical cable and wire rope are fixed again by cable, optical cable are laid along the direction of wire rope along electric pole.This mode is constructed quite complicated, and construction speed is slow and working security is relatively poor relatively.For this reason, so-called figure of eight optical cable has appearred in line cable industry, and it is with wire rope and unit cable or unit cable co-extrusion when producing, and like this, can finish by just once laying, and therefore, it is simpler to construct.Yet the fast development along with communication, power industry tends to hang up a lot of cables on the same wire rope, it be can't bear the heavy load, and will repeatedly lay.In addition, because the adjacent close together of existing power shaft tower and oneself are also quite firm, therefore, big like that before the tensile strength of required optical cable does not need.
The utility model content
Of the present utility modelly provide a kind of self-bearing type optoelectronic composite cable, it is to adopt following technical scheme to realize:
A kind of self-bearing type optoelectronic composite cable, it at least by: metallic conductor 1, coating 2, dowel 3, protection tube 4, optical waveguide 5, reinforcement 6 and sheath 7 are formed; Described metallic conductor 1 constitutes cable section with coating 2; described coating 2 is coated on outside the metallic conductor 1; described optical waveguide 5 is positioned at protection tube 4; be positioned at outside the reinforcement 6 in the described protection tube 4; described protection tube 4 constitutes optical communication element with reinforcement 6 and is positioned within the sheath 7; described dowel 3 is between coating 2 and sheath 7, and described coating 2, dowel 3 is one of the forming with sheath 7 and what adopt is commaterial, and described optical waveguide 5 has 1 at least.
Above-mentioned described metallic conductor 1 is single copper or other metal; Also can be the complex of many preformed metallic conductors.
Above-mentioned described protection tube 4, its material are polybutylene terephthalate or modified polypropene.
Above-mentioned described optical waveguide 5 is light transmitting fiber or optical fiber ribbon.
Above-mentioned described reinforcement 6, its material are that steel wire or glass fibre increase plastics (FRP).
Above-mentioned described coating 2, dowel 3, sheath 7, its material are plastics such as polyolefin, PVC.
The beneficial effects of the utility model: because the communication of this composite rope current collection power and optical communication be in one, and be formed in one, so more compact structure, cost more save, construct more convenient, lays number of times and can obviously reduce.
