The fourth extension to the Grande Dixence hydropower scheme -the new station at Bieudron, leaves all previous limits behind: the installed output from each of its three five-jet turbines is not less than 423 MW. The maximum head of 1,869 m also outclasses everything known previously. The scope of VA TECH HYDRO includes model investigation of the runners, design and supply of the five nozzle Pelton turbines with digital speed governors as well as the supply of three spherical valves with a rated diameter of 1,400 mm and design pressure 203 bars and manifolds. | ||||||||||||||||||||||||||||||||||||||||||||||||||
| Besides the Pelton turbines and the generators VA TECH HYDRO supplied the complete electrical equipment as well as main transformers, station service transformers, station service and unit auxilliary equipment , generator busbars, switch gears, protection and excitation equipment as well as the entire control and instrumentation of the power stations.
