Abstract
A wind power turbine for producing electric energy has a pylon extending from a bottom end to a top end; a nacelle fitted to the top end of the pylon to rotate about a first axis; an electric generator fitted to the nacelle to produce electric energy; a blade assembly, which rotates with respect to the nacelle about a second axis; an electric cable bundle extending from the electric generator to a point inside the pylon, such as at the bottom end of the pylon; and a guide device for guiding the cable bundle, and configured to divert the cable bundle radially from a point close to the first axis, to a point substantially away from the first axis.
Claims26
An electric energy producing wind power turbine comprising:
- a pylon extending from a bottom end to a top end;
- a nacelle fitted to the top end of the pylon and configured to rotate about a first axis;
- an electric generator fitted to the nacelle and configured to produce electric energy;
- a blade assembly configured to rotate with respect to the nacelle about a second axis;
- an electric cable bundle extending from the electric generator to a point inside the pylon;
- and
- a guide device connected to the cable bundle and including an elongated member articulated to extend along a designated guide path, wherein the cable bundle extends about the elongated member and the guide device is configured to guide the cable bundle to:
- (i) divert the cable bundle radially from a point close to the first axis to a point away from the first axis, and
- (ii) rotate the cable bundle, wherein a first end of the elongated member is fixed to the nacelle and is configured to rotate together with the nacelle and the cable bundle.
