GH20 Hydrogenerators are designed to meet the growing market for CGH's (Hydroelectric Power Plants). Their structure is lighter and more compact when compared to the previous GH10 line, with a reduction of about 70% in volume and 40% in length.
This reduction enables powerhouse optimization at a rate of 30% smaller in size, significantly reducing investments with infrastructure facilities.
Another advantage of the GH20 Hydrogenerator line is the possibility to skid-mount the Turbine-Generator set at the factory, reducing time and field mounting costs.
In addition, there other features that make the GH20 Hydro line more competitive and can be highlighted:
Brushless excitation (brushless and slip rings)
Low and medium voltage (electrical installation optimization)
VPI impregnation with epoxy resin
Sized according to turbine rated speed
Grease or oil lubricated bearings
Bearing design according to turbine axial and radial loads
Reduced Maintenance
Inertia sized based on turbine and hydraulic circuit characteristics
Inertia flywheel mounted on back side of the generator
Factory generator tests (efficiency test and temperature rise test)
Main technical features:
Output power: 300 to 3900 kVA
Nº of poles: 6 to 16
Frequency: 60 or 50 Hz
