Abstract: A gas-insulated switchgear is disclosed. The gas-insulated switchgear comprises: a housing (2) defining a housing volume (4) for holding a dielectric insulation gas, a conductor arrangement (10) arranged within the housing volume (4) and comprising a conductor section (12) to be cooled, a cooling system (20) for cooling the conductor section (12), the cooling system (20) comprising a spray generator (22) for generating a spray (30) directed at the conductor section (12), the spray (30) comprising liquid droplets of a cooling fluid suspended in the dielectric insulation gas, wherein the dielectric insulation gas is configured to be in a gaseous form at operating temperatures of -30°C and above, and wherein the cooling fluid is configured to have a boiling point of more than 70°C.
