Gear system:

Rotor blade: 3-stage planetary helical gear system (2 x planetary gears, 1 x helical gear) Designed acc. to the REpower gear system guideline meeting the most stringent requirements in terms of service life and quiet running Optimized efficiency Improved structure-borne sound insulation Low temperature level due to an efficient oil cooling system by means of an oil/air heat exchanger Three-stage oil filtering system for maximum oil quality Integrated oil particle counter

Load-optimized, light GRP construction Outstanding lightning protection due to multi-receptor system

Tube tower:

Optimal integration of the complete electrical system, consisting of the generator, converter and transformer, into the nacelle Reliable protection against moisture and sea air due to the air/air or water/air heat exchanger Low transmission losses due to the fact that the components are located close together Components mounted using elastomer bearings for structure-borne sound insulation and vibration damping Characteristic frequency of the tower is higher than the rotor’s rotating frequency; this ensures that the tower and nacelle are minimally loaded Entire speed range of the installation can be used as there is no frequency interference

Maximum component safety via T- and L-flanges as well as via load-optimized door openings
