Generators with water-cooled stators
and hydrogen-cooled rotors are optimal
for the highest output ranges. Their compact
design coupled with our unique direct
water-cooled stator is suitable for large
steam and nuclear power plant applications
ranging up to over 2000 MVA.
Technical features
Typically equal or more efficient than
equally rated air-cooled model
Smaller in size than equally rated
hydrogen- and air-cooled models
Not prone to contamination by dirt,
oil and humidity
Simple, low maintenance, primary water
system with demineralized/pH controlled
cooling water to suppress copper corrosion
Bracket bearings and shaft seals arranged
to minimize H? leakage
Frame arranged for ease of alignment
and foundation loading
Spring-mounted stator to minimize vibration
transmission to foundation
Pre-stressed, non-magnetic, through
bolts minimize the need for maintenance
and re-tensioning of the core
Stator bar tightness is maintained
with pre-stressed ripple springs to avoid
mechanical and electrical degradation
Stator end windings surrounded by a
glass-fiber cone for radial support
Water-cooled stator winding to maximize
output
High-pressure multi-stage compressor
blower for intense cooling
Hydrogen-cooled rotor winding for high
current (MVA) capability
