The hydrogen-cooled 24kV units were the one's I was most used to seeing.
Thanks, all. Very helpful.

Caption:"Above – Left: Some or all conductors in inner water-cooled bars are
hollow copper tubes. Example cross section is from a General Electric 200,535
kVA, *13.8 kV*, 3600 RPM unit.
Right: Non-conductive hollow steel tubes are used with inner gas-cooled bars.
Cross sections are from: (L) Westinghouse 493,280 kVA, *24 kV*, 3600 RPM inner
hydrogen-cooled unit, (C) Westinghouse 209,000 kVA, *13.8 kV*, 3600 RPM unit
inner hydrogen-cooled unit and (R) Westinghouse 159,000 kVA, 13.8 kV, 3600 RPM
inner air-cooled unit.
