The manufacturing level of 252 kV SF6gas insulated metal enclosed switchgear(GIS) all over the world is reviewed in this paper
especially a GIS with rated voltage of 252 kV
rated current of4 000 A and rated breaking current of 50 kA is introduced.The structure of the GIS is of three-pole circuit within one enclosure except the circuit breaker and the current transformer.The design
