Abstract (en)

[origin: WO2013104580A1] The invention relates to a wind turbine comprising - a rotor which rotates about a rotor axis, - rotor blades which converge in a central rotor hub and which are designed to be adjustable, - a transmission which is connected at least indirectly to the rotor on the drive side and at least indirectly to a generator on the output side, and - supply lines for adjustment energy, said supply lines being led through the transmission and into the rotor hub. The invention is characterized in that - the transmission comprises at least one planetary stage with a stationary planet carrier and - the supply lines for the adjustment energy run through the stationary planet carrier and through a supply channel arranged centrally about the rotor axis.
