A cable guiding structure () for a tower () of a wind turbine () is described. The tower has a height in substantially vertical direction () and a width in substantially horizontal direction (). The cable guiding structure () is adapted for guiding a cable () within the tower of the wind turbine. The cable guiding structure includes a horizontal movement element () at least partially movable in the width direction () of the tower (). The horizontal movement element () includes a receiving part () for receiving the at least one cable () of the wind turbine and wherein the horizontal movement element allows a movement of the at least one cable () in the width direction () of the tower (). Further, a method for mounting a cable guiding structure is described.

Cable guiding structure for a tower for a wind turbine, method for mounting a cable guiding structure, and wind turbine

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.
