[0002] Wires and cables are one of the essential materials for transporting electric energy. They are widely used in economic production. There are many ways to lay cables. The laying methods of cables mainly include: underground laying, laying cables along support frames, laying cables through cable protection pipes, laying cables on cable bridges, etc. Among them, laying cables through cable protection pipes is to lay the cable protection pipes in advance, and then pass the cables through the pipes. The inner diameter of the pipes cannot be less than 1.5 times the diameter of the cables. Generally, seamless steel pipes are used as cable protection pipes. Single-core cables cannot be laid through seamless steel pipes.

[0003] However, when the existing cables are installed, when the cables pass through the opening of the cable protection pipe, friction is easily generated between the cables and the pipe opening, which can easily cause wear of the cable skin. The cable skin is generally a protective layer of the cable, which mainly plays the role of protecting the cable conductor and the insulation layer. The wear also has a great impact on the service life and reliability of the cable. For this reason, a cable harness protection device is proposed. Utility Model Content
