[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. The cable protection tube is mainly installed in the area where the communication cable and the power line intersect to prevent the power line from being broken and causing a short circuit accident, causing the communication cable and wire rope to be energized, so as to protect the cable, switch, movement board, and even the whole machine from being burned out, and it also plays a certain isolation role in the magnetic field interference of the power line.

[0003] However, the current cable protection tube is troublesome to install, which greatly affects the progress of the installation. It is also very troublesome to replace and disassemble it after the installation is completed. It is very inconvenient to use and greatly increases the labor intensity of the staff.
