A conductor bar configuration includes a multiplicity of conductor bars extending along a longitudinal axis, stacked on one another along a vertical axis and each having four cooling ducts aligned parallel to the longitudinal axis, disposed next to one another in pairs in the direction of a transverse axis perpendicular to the longitudinal axis and to the vertical axis and disposed one behind another in pairs along the longitudinal axis. Each cooling duct has an associated orifice in the vicinity of one end of the configuration and reaches into one of two gas outlet zones disposed approximately in the middle relative to the longitudinal axis, where it merges into an outlet duct directed at an acute angle to the vertical axis. For each pair of cooling ducts situated next to one another in the case of each conductor bar, the orifice of one cooling duct is disposed directly at one end and the orifice of the other cooling duct is spaced from that end. For each pair of cooling ducts disposed one behind another the orifice of one cooling duct is disposed directly at that end to which it leads, and the orifice of the other cooling duct is spaced from that end to which it leads. A rotor assembly includes a multiplicity of identical configurations and is suitable for forming a rotor winding of an electric machine, in particular a turbogenerator. The conductor bars are interconnected by conductor bows disposed at each end and bent approximately in the shape of a circular arc about the longitudinal axis.
