15 Claims

1. A wind turbine, comprising:

a tower;

a nacelle supported rotatably at a top portion of the tower;

a main cable for transporting electrical energy produced in the nacelle to a bottom portion of the tower; and

at least one auxiliary cable guided from the nacelle to an intermediate portion between the top portion and the bottom portion and/or to the bottom portion of the tower;

wherein the main cable comprises a first loop, and the at least one auxiliary cable comprises a second loop, and the first loop and the second loop are configured for compensating, independently from each other, a movement of the respective cable due to a rotation of the nacelle relative to the tower;

wherein each of the first loop and the second loop comprises, in a direction along the respective cable, an upper attachment point at the nacelle, an intermediate attachment point in the tower for stopping a twisting movement of the respective cable, and a lower attachment point in the tower for stopping a twisting and vertical movement of the respective cable;

wherein a height of the intermediate attachment point of the main cable within the tower is different than a height of the intermediate attachment point of the at least one auxiliary cable within the tower.

14. A method for manufacturing a wind turbine comprising a tower, a nacelle supported rotatably at a top portion of the tower, a main cable for transporting electrical energy produced in the nacelle to a bottom portion of the tower, and at least one auxiliary cable guided from the nacelle to an intermediate portion between the top portion and the bottom portion and/or the bottom portion of the tower, wherein the main cable comprises a first loop and the at least one auxiliary cable comprises a second loop, the method comprising:

installing the at least one auxiliary cable with the second loop in the tower;

erecting the tower; and

installing the main cable with the first loop in the tower, wherein the first loop and the second loop are configured to compensate, independently from each other, a movement of the respective cable due to a rotation of the nacelle relative to the tower during operation of the wind turbine;
