ABSTRACT:
A metal-enclosed, gas-insulated switchgear assembly having at least one active part (19) is mounted in an enclosure extended along an axis (18). The active part (19) is provided on at least one side with a contact-making assembly (25). The contact-making assembly (25a) is electrically conductively connected to a connecting part (26) which is provided with a shielding electrode (28). The shielding electrode (28) is connected to a supporting element (35) which bounds an intermediate area (40). The supporting element (35) is connected, on the side facing away from the shielding electrode (28), to a fitting (37) which has holes (39) which originate from the intermediate area (40) and are designed to hold fixing screws. The connecting part (26) is designed for advantageously simply assembly. The connecting part (26) dielectrically shields the heads of the fixing screws.
