A gas-cooled turbo-generator has a pressure-tight casing with a stator disposed therein and a rotor. The turbo-generator also has cooling air feeders and dischargers disposed in the casing for circulating cooling air at a super atmospheric pressure in the casing. The stator and rotor have longitudinal slots for accommodating conductors and a proportion of conductor volume per longitudinal slot is at least twice a volume of the insulation. There is also provided an air/water heat exchanger for absorbing heat from the cooling air.
