[0001] The utility model relates to the technical field of electric power construction, in particular to a tool for making a high-voltage cable head for electric power installation. Background Art

[0002] In the process of power construction, when two cables need to be connected to each other, cable heads must first be made at the ends of the two cables, and the key step in making the cable head is to peel the cable ends to expose the wires inside the cables. In the prior art, the utility model patent with patent application number 201821612853.0 discloses a high-voltage cable head making tool for power installation, which is mainly composed of a clamping mechanism and a ring cutter. When stripping the end of the cable, the cable is first clamped and fixed by the clamping mechanism, and then the insulation layer of the cable is cut along the circular direction at the end of the cable by the ring cutter. The cut insulation layer on the cable is then pulled down on the cable to expose the wires inside the cable to make a cable head. The inventor believes that there are the following problems during use: although it can cut the insulation layer of the cable, it is still necessary to pull the insulation layer of the cable down on the cable. Due to the friction between the insulation layer and the wires inside the cable, it is difficult to pull the insulation layer of the cable end manually, which is labor-intensive and inconvenient to use.

This provides ease of use and enhanced convenience.
