Compact hydroelectric generators offer 70% more power density

WEG has launched two series of compact hydroelectric generators - GH11 and SH11 - claimed to have up to 70% more power density than previous models. With rated capacity from 500 to 18,000kVA, the GH11 and SH11 8-pole to 36-pole hydroelectric generators are available with frame sizes from IEC 630 to IEC 1800 and output voltages from 400V to 13.8kV at 50 or 60Hz.

The GH11 series is designed for standard applications with relatively small and simple turbines, while the robust SH11 series is designed to meet more demanding specifications for turbines and complex hydroelectric power stations. The SH11 generators have a modified mechanical and electrical design that allows them to be operated with higher inertial forces and relatively large axial and radial loads despite their compact construction.

WEG's generators can be installed and commissioned in existing plants as the design is based on a standard technology platform.As a result, the manufacturing process is similar to series production and meaning users benefit from shorter delivery times.

Both the GH11 and SH11 can be installed either horizontally or vertically and are available in versions for brushless excitation or static excitation with brushes.
