Problems solved by technology

However, due to its long-term operation, the silicone grease dries up and the friction force is extremely high. It is very difficult to disassemble, time-consuming and labor-intensive, and it is easy to damage the cable terminal accessories.
This leads to a large amount of time, manpower and material resources for cable maintenance and testing, and low efficiency of inspection work, which is not conducive to the safe and stable operation of the regional power grid.

Description

technical field [0001] The invention relates to the technical field of power cable testing, in particular to an auxiliary tool for cable testing with a T-shaped terminal. Background technique [0002] Cable terminals are frequently used equipment for cable transmission and distribution of electric energy. Plugging and unplugging is the method of its assembly and disassembly, and it is also a necessary work step for cable fault repairs and planned maintenance tests. Therefore, when testing cable equipment, it is necessary to frequently disassemble the cable terminal. However, after a long period of operation, the silicone grease dries up and the friction force is extremely high. Disassembly is very difficult, time-consuming and labor-intensive, and the cable terminal accessories are easily damaged. This leads to a lot of time, manpower and material resources for cable maintenance and testing, and low efficiency of inspection work, which is not conducive to the safe and stabl...
