The GIGATOP 2-pole turbogenerator from Alstom is a unit made with a water and hydrogen-cooled body and is useful for many steam turbine power plants. This is made with many quality features including a capacity of 400-1400 MW at 50 Hz and 340-1100 MW at 60 Hz. This is useful because it makes it easier for the unit to operate with care. It is a great continuation of technology that Alstom has been developing for more than a hundred years. This is a very efficient unit that works for all load sizes and a water-cooled rotor is made to make it easier to work in more conditions. It also keeps losses from being a serious threat. The triple-circuit sealer is also used to keep the unit protected and to get the hydrogen to stay pure and sturdy.
