Abstract (en)

[origin: EP0493134A1] A lightening arresting insulator with a pressure-release mechanism for releasing pressure when a lightening surge flows in a power transmission line is disclosed. The arresting insulator has a plurality of slits formed in the outer wall of an insulating cylinder formed from a material having a high voltage resistance. The slits extend lengthwise to form thin wall portions in the insulating cylinder. An elastic insulator is filled in each of the slits.
