Abstract

A gas-insulated switchgear apparatus including a three-phase circuit breaker, a three-phase disconnecting switch and a cable head, with the disconnecting switch and the cable head being accommodated in a cable head housing. To minimize the size of the disconnecting switch, movable insulators, connected to movable conductors, and stationary insulators, supporting connecting conductors, are arranged so that the movable and stationary insulators form triangles disposed substantially in the same plane with the respective triangles being inverted in relation to each other.
