Damp-proof and fire-resistant CPVC cable protection tube

Abstract

The invention relates to the technical field of cable protection tubes and further discloses a damp-proof and fire-resistant CPVC cable protection tube. The protection tube comprises an inner tube, wherein the inner tube is sleeved with an outer tube, an outer wall of the inner tube is fixedly connected with evenly-distributed connecting ribs, opposite sides of the connecting ribs are fixedly connected with the outer tube, an inner wall of the inner tube is fixedly connected with a wear-resisting layer, and evenly-distributed heat conducting fins are arranged outside the inner tube. The damp-proof and fire-resistant CPVC cable protection tube is advantaged in that a double-layer structure of the inner tube and the outer tube is arranged, a cable is placed in the inner tube, the heat-conducting fins between the inner tube and the outer tube can conduct and absorb heat, excessive heat on the inner tube and the outer tube is concentrated on the heat-conducting fins, so the heat on the inner tube and the outer tube is reduced, the more fire-resistant effect is achieved, gap heat conduction can be performed by arranging a gap between the inner tube and the outer tube, and water vapor can be prevented from entering the inner tube by arranging a drying layer, so the damp-proof effect is achieved, and convenience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of cable protection tubes, in particular to a moisture-proof and fire-resistant CPVC cable protection tube. Background technique [0002] The cable protection tube refers to a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. The communication cables and wire ropes are charged to protect the cables, switches and core boards, so that the whole machine will not be burned out, and it also plays a certain role in isolating the magnetic field interference of the power lines. [0003] However, the installation conditions of cables are mostly complicated. When metal pipe fittings such as steel pipes are selected as protective pipes, they are prone to moisture, which may cause short circuit of the cable and cause electric fires. A moisture-proof and fire-resistant CPVC cable protection tube is proposed to solve the above pr...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a moisture-proof and fire-resistant CPVC cable protection tube, which has the advantages of being moisture-proof and heat-resistant, and solves the problem that the installation conditions of cables are mostly complicated, and metal pipe fittings such as steel pipes are selected as the protection tube. It is easy to be affected by moisture, which may cause a short circuit of the cable and cause an electric fire. When the protective tube made of other materials is used, the heat dissipation effect is not good, and safety accidents may occur.
