PROBLEM TO BE SOLVED: To facilitate grounding rod lifting work in overhead wire construction by reducing an overall weight of grounding rods for electric overhead wire construction.SOLUTION: A grounding rod includes a grounding rod body 20, and a hook metal fitting 30 provided at the top end of the grounding rod body 20. The grounding rod body 20 is constituted by a plurality of hollow conductors 22 and conductor connection parts 24 for connecting the adjacent hollow conductors 22, and includes insulation coating layers 23 for coating part or the whole of conductor exposure parts of the grounding rod body 20 and a ground wire connection part 40 for connecting a ground wire 46 to the hollow conductors 22 near the lower part of the hollow conducts 22 of the grounding rod body 20. The conductor connection parts 24 consist of conductor coupling joints 24P for assembly and disassembly by a single-touch operation.SELECTED DRAWING: Figure 1
【課題】 架線工事用接地棒の全重量を軽減して架線工事の際に接地棒の持ち上げ作業を容易にすること。【解決手段】 接地棒本体20とこの接地棒本体20の上端に設けられたフック金具30とから成り、接地棒本体20は、複数の中空導体22と隣り合う中空導体22を接続する導体接続部24とによって構成され、接地棒本体20の導体露出部分の一部又は全部を被覆する絶縁被覆層23と接地棒本体20の中空導体22の下方付近で中空導体22にアース線46を接続すべきアース線接続部40とを備えている。導体接続部24は、ワンタッチで組立、解体することができる導体継手24Pから成っている。【選択図】図1
