WEG, a global leading manufacturer of motor, drive and power generation technology, has launched two new series of high quality compact hydroelectric generators, the GH11 and SH11.

The two generators come with up to 70 per cent more power density than previous models, said a statement from the company.

As a result, engineers can benefit from a low weight and space-saving solution for easier installation, it said.

The new generators are also available with shorter lead times thus helping hydroelectric power stations to reduce downtimes and increase productivity, it added.

With rated capacity from 500 to 18,000 kVA, 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 400 V to 13.8 kV at 50 or 60 Hz, said the statement.
 
The hydroelectric generators provide excellent reliable performance. 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. They can also withstand adverse conditions such as high continuous speeds or load shedding.
 
The company’s generators are easy to install and commission in existing plants because the design is based on a standard technology platform. WEG has standardised the production of the new generators and key components are provided in the preliminary design stage.  As a result, the manufacturing process is therefore similar to series production and end users can benefit from shorter delivery times. The generators are highly versatile and can be easily adapted to individual application specifications.  
 
Both the GH11 and SH11 can be installed either horizontally or vertically and are available in versions for brushless excitation (with or without an auxiliary exciter) or static excitation with brushes, it said.

Marek Lukaszczyk, European and Middle East marketing manager at WEG, said: “We are committed to helping customers increase efficiencies throughout its process, and this includes reducing downtime.”

“By delivering products to customers as fast as possible means they can get their process up and running quickly, therefore maximising productivity and profitability,” he added. – TradeArabia News Service
