A wind energy installation includes a tower and a nacelle arranged at the top of the tower such that it can swivel in the azimuth direction. The installation also includes a plurality of cables which are guided via a loop from the tower into the nacelle, the cables being held at a distance from one another in the loop by means of rotationally fixed and loose holders. The holders each have receptacles for attachment of the cables with a predetermined circumferential separation. The holders include a lower rotationally fixed guide ring and an aligning upper loose guide ring. A loop guide is formed such that the loop is subdivided by means of the rotationally fixed lower guide ring into a curved untwisted area and an extended twisted area.
