Technical field
The utility model relates to cable protection technical field, is specifically related to a kind of cable sheath tube.
Background technology
At present laying field at power transmission line is mainly that the pipeline that common plastic material is made adopts the mode of directly sunkening cord to carry out cabling, but the pipeline that common plastic material is made in the middle of practical application is easy to run into a lot of problems, such as:
1, the flexibility of conventional pipelines is poor is easy to cause pipeline break, and the rigidity of pipeline is low so that the weight bearing power of pipeline is very poor;
2, conventional pipelines is owing to adopting common plastic cement material to make, and its acid and alkali-resistance corrosion resistance is poor, is easily corroded, and affects the use of pipeline;
3, when excess Temperature or when too low, conventional pipelines is easy to occur quality problems, even fracture;
4, traditional pipeline radiation hardness, ageing resistace is bad, useful life is short, poor fire.
Be more than the some shortcomings of traditional pipeline, but be but easy to cause pipeline normally to use, more serious may damage cable, causes the fault of power transmission line, bring very large economic loss, traditional cable transfer pipeline can not meet the needs of modern social development.
Utility model content
The purpose of this utility model is for having solved above-mentioned existing technical disadvantages, and the utility model provides a kind of superior performance, the cable sheath tube of long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cable sheath tube, the interface end and the female end that include protecting pipe body, be connected with protecting pipe body, the skin that described protecting pipe body comprises endosexine and is composited with described endosexine one, described outer field thickness is more than or equal to the thickness of endosexine, described endosexine is PVC plastic layer or PE plastic layer or MPP plastic layer, and described skin is frp layer.
Preferably: described frp layer is entwined by glass fiber impregnated flame-retarded resin.
Preferably: in described interface end, be also equipped with at least one groove, described groove has been embedded in sealing ring; Described female end is that the protecting pipe one end that is arranged on made from this body by integral forming of protecting pipe has the extended pipeline of caliber.
Preferably: the position joining at described interface end and protecting pipe body is also provided with positive stop lug boss, and the external diameter of described positive stop lug boss is suitable with the external diameter of described female end.
Preferably: described outer field surface is also provided with reinforcing rib structure.
Preferably: described outer field surface is also coated with anti-aging or fire-retardant auxiliary agent.
Useful technique effect of the present invention is: in the technical solution of the utility model, by the skin of protecting pipe body being arranged to comprise endosexine and be composited with endosexine, the weight that the endosexine of PVC plastic layer or PE plastic layer or MPP plastic layer makes protecting pipe is lighter, increase useful life, acid and alkali-resistance corrosion resistance is strong, compound described skin is frp layer, described outer field thickness is more than or equal to the thickness of endosexine, weight bearing power is strong, there is lightweight, easily construction, good airproof performance, composite performance is stable, good flame resistance, the features such as long service life.
