Abstract: The present invention relates to gas-insulated electrical apparatuses (10), in particular gas-insulated transformers (101) or reactors, comprising a housing (12) enclosing an interior space (14), in which an electrical component (16) comprising a winding (18, 20) is arranged, at least a portion of the interior space (14) defining an insulation space (24) which is filled with an insulation fluid (26) electrically insulating at least a part of the electrical component (16) from the housing (12). According to the invention, the electrical apparatus (10; 101) further comprises a cooling element (28) comprising a condenser (36), an evaporator (30) and a cooling fluid (32) to be circulated between the condenser (36) and the evaporator (30). The evaporator (30) is designed such that at least a part of the electrical component (16) is immersed in the cooling fluid (32) in its liquid state, thus being in direct contact with the cooling fluid (32).
