Abstract:
A high-voltage bushing comprising:an electrical conductor to which high voltage can be applied; a varistor arrangement surrounding one section of the electrical conductor; two electrical connections, one for connection to high voltage and the other for connection to ground; a bushing insulator provided between the electrical conductor and the varistor arrangement, the bushing insulator being in the form of a molding and having a supporting element, provided with a guide surface, for a contact connected to the electrical conductor, in a plug connection to a cable or to a housing bushing of an electrical apparatus; an insulator housing for accommodating the varistor arrangement; and a clamping apparatus for applying a contact force to the electrical connections and to the varistor arrangement located in between them like a sandwich, the clamping apparatus having an insulating part configured using at least one of an insulating cylinder and a tensioning strip formed as a loop to apply the contact force to the two electrical connections independently from the insulator housing.
