Abstract

The invention relates to a gas-cooled electrical device (), especially a gas-cooled generator, which comprises at least a rotor (), a stator () and also a stator casing () which encloses this stator, and an end-winding space (). In this case, passages for a cooling gas are provided both in the rotor () and in the stator (), wherein the end-winding space (), especially connectors () and/or output conductors () which are arranged therein, are impinged by at least some of the cooling gas flow () which issues from the rotor (). In order to be able to achieve an especially concentrated and controlled cooling, at least the connectors () and the output conductors () are arranged in the working area of at least one guiding device () which guides the cooling gas flow ().
