Beschreibung
Zusammenfassung:	A nacelle of a wind power plant is presented comprising a generator (1), a rotor provided with rotating blades and an adjustment device for the blade angle, a gearbox (2) for changing the rotation speed of the rotor such that it will be suitable for the generator, a cable duct (3) passing through the gearbox and rotating with the rotor, through which cable duct passes a power supply cable (4) for the blade angle adjustment device, and a slip ring unit (5) for connecting the power supply cable rotating with the rotor to the fixed power supply. In accordance with the invention, an air flow is arranged inside the cable duct (3) for cooling the power supply cable (4).
