Abstract
The surge arrester has an axially symmetrical active portion (2) arranged between two connection fittings (1, 2). This active portion (2) contains varistor elements (12) stacked one above the other and also an axially symmetrical connecting element (13) of electrically conductive material arranged in the active portion (2) of the arrester between two successive varistor elements (12). At least four mounting places (16, 16'), which are uniformly distributed around the axis in the circumferential direction, are formed in the connecting element (13). Two first (16) of the mounting places support respectively one of two first loops (15) which act with contact force on the connecting element (13) and on the varistor elements (12) abutting the connecting element (13). Two second (16') of the mounting places support respectively one of two second loops (15) which act with contact force on the connecting element (13) and on the varistor elements (12) located under the connecting element. Such a surge arrester can have large constructional heights and is distinguished in addition by good mechanical and electrical properties.
