Patent ID: 11371489

Abstract:
A tower for a wind turbine is disclosed, said wind turbine comprises the tower, a nacelle and a rotor having at least one rotor blade. The tower is configured for supporting the nacelle and the rotor on a support system. The tower itself may be structured as having an upper top end for supporting the nacelle and a lower support end for being placed on the support system. Electric energy generated is transported via power cables from the nacelle to an electric grid, preferably via power electronic components, switches and/or transformers. Furthermore, the nacelle may rotate around the yaw axis according to the current wind direction. Hence, the rotation of the nacelle introduces a twist into the power cables, wherein said twist causes a deviation (shortening) in the length of the power cables. Furthermore, the tower comprises at least one radial cable guiding device for receiving the cable and a cable support arrangement for supporting the cable in a beneficial manner. Additionally, the tower comprises anti-torsion fixation means configured for reducing and/or preventing a propagation of a cable twist of the cables of a hanging portion into power cables of a loop portion. The power cables comprise a hanging portion having a cable axis, a cable loop portion having a horizontal cable loop, and the supported portion being at least partially supported by the cable support arrangement.
