[0002] Cable pressure tube is a pipe used to protect power cables. It provides mechanical protection and insulation performance of cables under various environmental conditions. Cable pressure tube is usually made of pressure-resistant and corrosion-resistant materials, such as metal (such as steel, aluminum) or plastic (such as polyvinyl chloride PVC, polyethylene PE).

[0003] However, the existing cable pressure tubes have the following problems during use: the existing cable pressure tubes are mostly pressure-resistant by the strength of the pressure tubes themselves, and they have strong hardness. This leads to stricter requirements for the direction of the cables, which are usually linear and difficult to adjust according to the laying needs of the cables. There is usually a gap between the pressure tube and the internal cables, and the pressure is too large, which will cause the pressure tube to be damaged and collapsed. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content
