Description

Technical Field

[0001] The invention belongs to the technical field of cable tools, and in particular relates to a cable pipe protection device. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They are often used in urban underground power grids and power station lead-out lines. With the rapid development of science and technology, power cables are increasingly used. At present, there are no special laying tools in the laying process of power cables. They are often laid by manual pulling. During the laying process, the outer skin of the cable is easily damaged by friction, which affects the safe operation of the cable. Therefore, cable protection tubes are currently used to protect them. At present, the cable protection tubes used are mostly steel tubes and PVC tubes. During the cable laying process, the protection tubes often need to be cut with a pipe cutter, electric saw or gas. The incision is not smooth, and some sections are sharp. It is very easy to scratch the cable insulation layer due to the intense friction between the end face of the protective tube and the cable during the cable pipe threading or cable pole laying process, especially when there is a bending angle, which directly affects the electrical insulation performance and power supply safety performance of the cable. In addition, the human pulling can damage the cable due to the uncontrollable force, which will bury safety hazards for future use, further affecting the service life of the cable and even causing safety accidents.
