SWITCHGEAR WITH SINGLE-PHASE INSULATION COMPRISING AIR AND SCREENS

Switchgear for high voltage comprising a circuit breaker (2) of vacuum breaker type and a disconnector (7) arranged above each other in a single-phase insulated design. Operating shafts (3, 9) are arranged for the circuit breaker and the disconnector, respectively. Two different types of single-phase insulation is used for the circuit breaker and disconnector unit and for phase lines (8) going out from the switchgear. The single-phase insulation consists of air insulation and screen walls (6) between the phases of the circuit breaker and disconnector unit (2, 7) and of synthetic material, preferably shrinkable plastic (14), on the surface of the outgoing phase line (8).
