PROBLEM TO BE SOLVED: To prevent insulators that are fitted to high-voltage drop wire support hardware, from being damaged by a second indirect hot-line tool when fitting the high-voltage drop wire support hardware to an end of a crossarm.SOLUTION: High-voltage drop wire support hardware 1 comprises: a crossarm holding part which is fitted to an end of a crossarm of a pole; and an insulator support arm 6 which are fixed at a distal end of the crossarm holding part for supporting a plurality of insulators 4 and a high-voltage drop wire. In the crossarm holding part, a first crimp part is fitted which is crimped by a first tip tool at a tip of a first indirect hot-line tool. In the insulator support arm 6, a second crimp part 40 is fitted which is crimped by a second tip tool 24 at a tip of a second indirect hot-line tool 39. In the state where the second crimp part 40 is crimped by the second tip tool 24, a space is secured between the insulator 4 that is supported by the insulator support arm 6 and the second tip tool 24 in such a manner that the second tip tool 24 is brought into contact with the insulator 4 even if a crimp position of the second tip tool 24 is displaced.SELECTED DRAWING: Figure 3 |
