Anti-damage cable protective sleeve convenient to penetrate through

Abstract

The invention relates to the technical field of cable protection sleeves, and discloses a convenient-to-penetrate anti-damage cable protection sleeve, which comprises a cable body, wherein an inner sliding layer is arranged on the outer surface of the cable body, a plurality of balls capable of rolling freely are annularly arranged on the inner wall of the inner sliding layer at intervals, more than half of the balls are embedded into the inner sliding layer, an insulating layer is arranged on the outer surface of the inner sliding layer, a shielding layer is arranged on the outer surface of the insulating layer, a high-temperature-resistant layer is arranged on the outer surface of the shielding layer, a corrosion-resistant layer is arranged on the outer surface of the high-temperature-resistant layer, and a hard layer is arranged on the outer surface of the corrosion-resistant layer. According to the invention, the inner sliding layer is arranged, a plurality of circular holes are formed in the inner wall of the inner sliding layer at intervals in the circumferential direction, and a plurality of balls capable of rolling freely are arranged in the circular holes, so that the resistance of a cable penetrating into the cable protection sleeve is greatly reduced, the cable can be smoothly arranged in the cable protection sleeve body in a penetrating manner, and the cable is prevented from being twisted and damaged in the penetrating process so as to avoid potential safety hazard.

Description

Technical field[0001]The invention belongs to the technical field of cable protection tubes, and specifically relates to a damage-resistant cable protection sleeve that is easy to wear.Background technique[0002]A cable is an insulated wire composed of one or more mutually insulated conductive cores placed in a sealed sheath. It is the most common transmission medium in power systems and communication systems. Because the production cost and use value of the cable are high, and the cable leakage has a greater safety hazard, the cables are generally buried from the ground to the bottom. In order to protect the cables, a cable protective sleeve must be placed in the cable jacket in advance. .[0003]Cable protective sleeve is a new type of casing material popularized and used in power engineering. With the rapid development of power cable buried laying projects, higher requirements are put forward for cable sleeves. The cable protective sleeve is made of polyethylene PE and high-quality ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides an anti-damage cable protective sheath that is easy to wear, so as to solve the twisting and bending of the cable proposed in the above background technology, which will cause the insulation performance and electrical performance of the cable accessories to be reduced, and it is difficult to be used by the operator. It was found that the operation accident occurred shortly after the cable accessories were installed and put into operation, which caused great safety hazards
