Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, and more particularly to a high-strength HDPE cable protection tube. Background Art

[0002] A high-strength HDPE cable protection tube is a cable sheath tube made of high-density polyethylene (HDPE) material. It has excellent physical and chemical properties and is suitable for various cable protection occasions.

[0003] In the existing technology, firstly, the cables of some devices may not be stably fixed in the protective tube, resulting in damage to the cables during transportation or installation. The cables at the connection of the tube body may be exposed to the outside and easily affected by mechanical damage, environmental factors, and human damage, reducing the service life of the cables. Secondly, the cables of some devices may not be able to obtain proper tension, affecting the performance and transmission efficiency of the cables. The cables may not be evenly distributed in the protective tube, resulting in increased friction between the cables, affecting the service life of the cables. It is difficult for operators to achieve precise control of the cable tension, reducing the flexibility and efficiency of the operation. Finally, some devices may lack sufficient auxiliary force during the tightening process of the cables, resulting in insufficient tightening of the cables, affecting the performance of the cables. The cables may be offset or twisted during the tightening process, affecting the stability and uniformity of the cables. Utility Model Content
