The present invention relates to gas-insulated electrical apparatuses, in particular gas-insulated transformers or reactors, comprising a housing enclosing an interior space, in which an electrical component comprising a winding is arranged, at least a portion of the interior space defining an insulation space which is filled with an insulation fluid electrically insulating at least a part of the electrical component from the housing. According to the invention, the electrical apparatus further comprises a cooling element comprising a condenser, an evaporator and a cooling fluid to be circulated between the condenser and the evaporator. The evaporator is designed such that at least a part of the electric component is immersed in the cooling fluid in its liquid state, thus being in direct contact with the cooling fluid.
