A GIS (Gas Insulated Switchgear) includes a main bus compartment including a main bus-bar unit, a transfer bus compartment including a transfer bus-bar unit, a sealed circuit breaker compartment including a circuit breaker unit and a load side compartment including a current transforming unit and a transfer bus conductor electrically coupling the transfer bus-bar unit and the current transformer unit. The circuit breaker unit is contained in the sealed circuit breaker compartment being separately independent from other compartments. The transfer bus conductor passes from the transfer bus-bar unit through the load side compartment to the current transformer unit without passing through the circuit breaker compartment. The sealed circuit breaker compartment and the load side compartment do not share insulating gas.
