Abstract: A coupling electrode for capacitive voltage tapping within an insulating body of a component which has at least one conductor section which is embedded in the insulating body and to which a high-voltage potential can be applied, having an electrode section which is composed of a semiconductive plastic, and having a connecting element which is electrically connected to the electrode section and is designed such that it can be passed out of the insulating body. A holder which is composed of a non-conductive material and, is connected to the electrode section and has the positioning means, which allow isolated mounting of the electrode section.

Abstract: A fuse box closure in a fuse assembly of a switch disconnector system, having a fuse cover which detachably closes the fuse box, a fuse-carrier part for accommodating the contact stud of a fusible link being detachably connected to the fuse cover. In the proximity of the outwardly facing fuse carrier, the fuse box is provided with a cylindrical annular groove with which a cylindrical annular contour of the fuse cover engages with form locking in the closed state.

Abstract: A gas-insulating switching unit includes a gas-filled housing containing a multi-pole vacuum switch and a three-position circuit breaker arranged below it. The vacuum switch is arranged so that the longitudinal axes of the horizontally positioned vacuum switching tubes are perpendicular to the front wall of the housing. The switch shaft of the circuit breaker is parallel to the front wall of the housing. Actuating rods are sealed against the front wall be bellows and can be used to operate the vacuum switching tubes. The circuit breaker is operated by a drive device via two pivoting levers that can be coupled by means of a fork opening.
