Description

Technical Field

[0001] This utility model relates to the field of cables, specifically to a cable burial protection pipe. Background Technology

[0002] Cable protection pipes are metal protective tubes with a certain mechanical strength, laid on the outer layer of cables to prevent damage. They are mainly installed at intersections where communication cables and power lines cross to prevent short circuits caused by power line breaks, which could energize communication cables and steel cables. This protects cables, switches, circuit boards, and even the entire device from burning out, and also provides some isolation against magnetic field interference from power lines.

[0003] Cable protection pipes have high current carrying capacity and low thermal resistance. During use, the friction coefficient between the cable protection pipe and the cable is low, making cable passage easier. Currently, traditional cable protection pipes cannot be easily disassembled and reassembled in actual use, requiring extensive replacement when damaged, wasting considerable time and increasing labor costs.
