Abstract

In a three-electrode surge arrester where the center electrode (3) is provided with a connecting wire (6) that projects outward radially and is provided with an outside short-circuit device, the latter consists of a two-arm spring clip (20) whose arms project axially beyond the free ends of the end electrodes and are in contact with the outside peripheral edge of the respective end electrode (1, 2) with a layer of insulating film (21) in between. Spring clip (20) has an roof-shaped arch (24) and is provided with a passage in the area of this arch that serves to secure the spring clip on connecting wire (6) of center electrode (3).
