• the cables are fixedly arranged in a lower part of the tower, preferably by means of cable clamps on the tower wall.
• the cables are led from the tower wall via a cable support into a radially central area of the tower interior. From there, the cables then run centrally and freely suspended to an upper end of the tower into the machine house.
• the cables are passed through a pipe, preferably a PE pipe, and through a round opening in the uppermost platform of the tower. By guiding the cables through the tube, the cables are collected in a large bundle. Bundling can lead to reduced current carrying capacity of the cables due to mutual induction of the dense current-carrying cables.
• the nacelle now rotates around its own axis several times because of the wind tracking, the cables twist and this leads to a shortening of the cables. This can lead to damage or wear of the insulation by friction between the individual cables, creating a high security risk is generated.

Due to the twisting of the cable, the cable bundle shortens in the axial direction. In order to prevent free rotation of the machine house by a distortion of the cables, or the cables would be damaged, the cables are guided in the cable loop. The shortening of the cable bundle is compensated by the excess of cable in the cable loop.
