C-PVC power cable protection pipe

Abstract

The invention discloses a C-PVC power cable protection pipe which comprises an outer pipe, an inner pipe is arranged in the outer pipe, a supporting assembly is arranged between the surface of the inner pipe and the inner wall of the outer pipe, and a limiting assembly is arranged on the surface of the outer pipe. And the inner pipe comprises an outer waterproof layer, an outer shielding layer, an aluminum silicate fiber felt, a flame-retardant layer, an inner shielding layer, an inner waterproof layer and a wear-resistant layer. The invention relates to the technical field of cable protection pipes. According to the C-PVC power cable protection pipe, the anti-pressure capability of the protection pipe can be effectively improved through the supporting assembly, so that the protection pipe is not prone to deformation and breakage, when multiple protection pipes need to be fixed into a bundle, the adjacent protection pipes are connected through limiting strips and limiting grooves, then the protection pipes are fixed through binding belts along annular grooves, the binding belts are not easy to slide and shift, so that the fixing effect is improved, the protection tubes are not easy to loosen, the stability is relatively good, and the protection pipe has good waterproof, shielding and high-temperature-resistant performances.

Description

technical field [0001] The invention relates to the technical field of cable protection tubes, in particular to a C-PVC power cable protection tube. Background technique [0002] Cable protection tube is also known as cable tube, power cable tube, cement cable tube, power row tube, power cable protection tube, etc. The cable protection tube is mainly installed at the intersection of communication cables and power lines to prevent short-circuit accidents caused by disconnection of power lines, causing communication cables and steel wire ropes to be charged, so as to protect cables, switches, core boards, and the whole machine from being burned out. Magnetic field interference also plays a certain isolation role. With the development of the times, composite materials made of cement or other non-metallic materials are gradually replaced by FRP. Most cable protection tubes made of FRP can improve its corrosion resistance in the ground. And life, with a smooth surface, outstandi...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a C-PVC power cable protection tube, which solves the problem of poor compressive performance and easy deformation or breakage, thereby causing damage to the internal cables, and when multiple protection tubes need When fixing in a bundle, it is often difficult to fix because the surface of the protective tube is smooth and there are no binding points
