Advanced technology

Equipped with advanced calculation tools and state-of-the-art lab facilities, the centre provides high levels of expertise in:

Standard & customer-made designs

Hydraulics and Mechanics

Governor systems

Measurement

Product performance

Turbine Technology Centre -- Grenoble, France

5 test rigs for all types of turbines

Advanced technology

Naussac 2 (8 MW, France) new runner design with oil free technology helps reduce water pollution caused by oils

Environment-friendly turbine designs

Green Turbine –Fish friendly Kaplan

Hooped Pelton

Vortex Turbine

Advance technology - Hooped Pelton

Advantages:

Bucket & hoops totally machined,low level of fatigue

No vibrations,low “ventilation” losses

Easier access before erection

Reduction of manufacturing time cycle and risk

No more stops for inspection, easy repairs

Hooped Pelton - an alternative to the traditional integral casting runner, with separated buckets inserted into two hoops for optimal efficiency.

Advanced technology

Generator Technology Centre - Birr, Switzerland

With its highly sophisticated support tools and new materials, the centre aimsat improving the overall technical quality and performance of our generator products. Ist competences is active in the fields of:

Electricity

Advanced mechanical design

Cooling and ventilation

IT tools, insulation technology and new materials

Continuous investigations by finite elementcalculation (electrical and mechanical)

Advanced technology

Oblique Elements - A unique Generator design feature

Overall benefits:Lower maintenance costsReduced material stresses in the foundation and generator Longer life expectancyAbsolute operating reliability Better performance & increased availabilityAvoidance of damage from short-circuits

Advanced technology

Generator design features

Stator with Oblique Elements Guaranteed concentricity and stability (without maintenance)Prevent buckling of stator coreReduce forces to the foundation

Rotor with Oblique ElementsHigh concentric stabilityHigh resilience to radial thermal expansion forces

Stator pressing system with central boltsPrevent any buckling or loosing of core during whole life timeHigh, uniform pressure is ensured

Self pumping bearing padsNo auxiliary oil pumps (oil flow ~speed)Less maintenance

Turnkey capabilities

Project management Leadership in execution of turnkey projects, interfacing with all parties. A single point of contact for clients

Design, engineering, Total plant capability for all types of hydropower plants, from either high or low head: storage, pumped-storage, refurbishment, to run-of-the-river scheme

Manufacture World-wide manufacturing sites ensure cost efficiency and facilitate financing optimisation

Erection, testing, commissioning

Innovative financing schemes
