[0002] Overhead power transmission lines are erected on the ground, using insulators and air-insulated power lines. Overhead lines are composed of conductors, overhead ground wires, insulator strings, poles, grounding devices and other parts. Overhead power transmission lines mainly use connecting pipes when connecting jumpers. At present, there are two main types of connecting tools for jumpers of overhead power transmission lines, one is a bolt parallel groove clamp, and the other is a hydraulic connecting pipe.

[0003] China Patent Authorization Announcement No.: CN219498922U, provides an overhead power transmission line jumper joint pipe, this patent puts a protective shell on the wiring device, the fixing column will fix the wiring device, the rotating threaded sleeve will lock the protective shell to prevent the protective shell from falling off, and a first sealing sleeve is fixed on one side of the threaded sleeve by a screw. The first sealing sleeve will prevent rainwater from entering the interior and corroding and damaging the internal parts. With the protection of the protective shell and other parts, the life of the joint pipe is greatly increased, eliminating the trouble of frequent replacement.
