ある。 The present invention has the configuration as exemplified above, and is provided with a parallel recess 12 into which the arrester element 15 is inserted, adjacent to the downward recess into which the fixed electrode of the main body insulator 2 is mounted. Although a bulge is produced on the side of the main insulator 2 in order to form the main body insulator 2, a sufficiently wide and high hollow parallel recess 12 can be formed thereby to facilitate the insertion of the arrester element 15.
Moreover, the mounting dimensions of the air switch, in which an appropriate number of main body insulators 2 and movable insulators 7 are assembled on the upper frame and the movable insulator mounting frame, can be made the same as before, and the arrester with lightning protection is built-in. An air switch can be easily constructed. Further, even when the air switch is mounted on the pole, the arrester element 15 can be replaced from below the main body insulator 2 while paying attention to insulation.
