The bushing has an electrical conductor (1) to which high voltage can be applied. One section of the electrical conductor (1) is surrounded by a varistor arrangement (9). The bushing also contains two electrical connections (4, 6), one (6) of which can be connected to high voltage and the other (4) can be connected to ground, a bushing insulator (5) provided between the electrical conductor (1) and the varistor arrangement (9), and a clamping apparatus (11) which applies a contact force to the electrical connections (4, 6) and to the varistor arrangement (9) located in between them like a sandwich. The clamping apparatus has an insulating part which applies the contact force to the two electrical connections. The bushing insulator is in the form of a molding and has a supporting element, provided with a guide surface, for a contact (1a) (which is connected to the electrical conductor (1)) in a plug connection to a cable or to an apparatus bushing of an electrical apparatus.
