A planetary gearbox (101) for a renewable energy turbine is disclosed. The gearbox comprises a planetary gearbox (101) and at least one service cable (110) extending through said planetary gearbox. For example, the service cable (110) may be for the supply of power to and/or data from a rotor of a turbine. The service cable (110) enters the gearbox (101) through a fixed planet stage (106c) of the gearbox and extends through a central shaft (130) to the stationary portion of a slip ring (120) assembly for providing, in use, a connection to a rotor of a turbine. The central shaft (130) may for example extend only partially through the gearbox. The service cable (110) may, for example, enter the output side of the gearbox at a location which is radially offset from the central axis of the gearbox. |
