You will never get out of 25. Further, the inner surface of the insulating cover 16 is provided with a non-slip portion 18 formed of a plurality of protrusions 18a, and the inner surfaces of both edges 16b and 16c of the insulating cover 16 are provided with anti-slip 19a and 19b. The insulating cover 16 that protects the charging portion 26a of the high-voltage line 26 does not move from the charging portion 26a and the charging portion 26a is not exposed, and the insulating cover 16 hangs down, or both edges of the insulating cover 16 are exposed. 16b and 16c do not spread. Therefore, it is possible to prevent the occurrence of ground faults and short circuit accidents in various operations, and the safety of workers can be ensured.

  In the above description, the first clip 2 is held by the high voltage line 26 by sandwiching the high voltage line 26 with the first clip 2. However, a hook is provided on the first clip 2, and the hook is connected to the high voltage line 26. You may comprise so that the 1st clip 2 may be hold | maintained to the high voltage | pressure line 26 by hooking.

  In addition, the second clip 7 is held by the pull-down insulated wire 31 by sandwiching the pull-down insulated wire 31 with the second clip 7, but a hook is provided on the second clip 7 and the hook is insulated for pull-down. You may comprise so that the 2nd clip 7 may be hold | maintained at the insulated wire 31 for pulling down by hooking on the electric wire 31. FIG.

  Moreover, by preparing indirect hot-wire tools 1 of a plurality of types (for example, three types of red, white, and blue) that are color-coded, it is possible to use indirect hot-wire tools of different colors for each phase. It is possible to prevent erroneous connection of the high-voltage underline edge line.
