Abstract
The surge arrester has a cylindrically symmetrical housing which can be grounded and through which a plug connection is passed which can be brought to a high-voltage potential. An active part which is aligned along the axis of symmetry is arranged in the housing and has two connection fittings and at least one varistor element arranged between the two connection fittings. The connection fittings and the at least one varistor element are braced with respect to one another by at least one loop forming a contact force. The insulation between the active part and the housing is ensured by a dielectric sleeve. The housing is in the form of a dielectric sleeve. The housing is in the form of a bottle and has a housing section in the form of a bottle neck, in which an electrical conductor is routed, which is connected to one of the two connection fittings, is electrically conductively connected to the plug connection, and is cylindrically symmetrical.
