Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tubes, and in particular to a cable with strong pressure resistance. Background Art

[0002] 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. Cable protection tubes are mainly installed in areas where communication cables and power lines intersect to prevent power lines from being broken and causing short circuit accidents, causing communication cables and wire ropes to be electrified, so as to protect cables, switches, movement boards, and even the entire machine from being burned out, and also play a certain isolation role in the magnetic field interference of power lines. There are currently two types of power cable pipes on the market: PE and MPP. Compared with PE power pipes, MPP power pipes have good high temperature resistance because the melting point of MPP materials is relatively high, the elastic modulus of the material is larger, and the wear resistance coefficient is higher. The physical and mechanical properties of the product are better than those of PE, and it is suitable for use as a protective pipe for high-voltage and high-temperature power cables. Therefore, the high-voltage power protection pipes used in the market are basically modified polypropylene (MPP) pipes. However, MPP pipes also have shortcomings such as insufficient strength and poor compressive resistance. They cannot provide better protection for cables during use, especially in certain locations that need to be fixed. Currently, using tools to directly fix the cables will cause excessive squeezing and breakage.

[0003] Therefore, improvements are made to address the above problems. Utility Model Content

[0032] In this embodiment, in order to achieve the effect of compressive resistance for the cable fixing position, a compressive protection component 3 is designed, and an internal thread layer 3-1 is provided inside both ends of the fixing sleeve 2, and two clamping rings 3-3 are mounted on the outside of the cable sheath 1 at both ends of the fixing sleeve 2.

The outside of the fixed sleeve 2 is also provided with two semicircular support sleeves 3-6. The surface of the support sleeve 3-6 is provided with a slot 3-7 and a socket 3-8.
