The utility model provides an asymmetric puncture electrode for $puncturing type arrester, the electrode by puncture fastener (1), lead arc foot (2) and insulating boot (3) are constituteed. Cable cleat install is on 10kV insulated wire in the puncture, leads the arc foot and installs in the 10kV insulated wire below, the cover can endure certain electric arc in its outside at puncture fastener (1) with after leading arc foot (2) equipment completion for insulating boot (3), has solved high-pressure puncture electrode and has made local the exposing of insulated wire and have the problem of insulating defect. The puncture fastener by top board, well clamp plate, holding down plate, be equipped with the jack panel and the combination of pressure nut forms, the higher authority of well clamp plate and the following semi-circular husband of kazakhstan who has three the top of the horn teeth respectively of top board for clamping insulated wire. The utility model discloses can take place under the circumstances that lightning arrester body damaged, the clearance punctures again, lead the arc foot through asymmetrical and dredge power frequency afterflow electric arc to burning certainly on one's body to pilot arc is skew wire not only, keeps away from the insulator moreover and outwards drifts about.
