Abstract

固定ブッシングの受容口内周面と絶縁筒の先端部外周面間の界面における面圧を確保する。 本発明におけるアレスタは、先端部に導体２を有する絶縁筒１と、絶縁筒１内に高圧電極３を介して挿入されるアレスタ素子積層体４と、アレスタ素子積層体４の後端部側に配設される接地電極５と、接地電極５の後端部側に絶縁筒１と同心状に配設されるコイル状のスプリング８と、絶縁筒１、接地電極５およびスプリング８を包囲する金属ケース６と、金属ケース６の後端部側の開口部に装着される封止部材７とを備えている。 　絶縁筒１の後端部側の外径は絶縁筒１の中央部側の外径よりも小径とされている。また、絶縁筒１の先端部１１の外周にはテーパ外面１３が設けられている。
