A wind turbine is provided, with a tower with a longitudinal axis, a nacelle on the tower, multiple power cables which extend from the nacelle into the tower and a transport unit. The transport unit is fastened inside the nacelle and serves to transport loads inside the tower to the nacelle. The transport unit has a cable guide unit with multiple rings, wherein the power cables are fastened to the circumference of the rings so that a region inside the rings is kept free for transporting the load. A top ring is fastened to the nacelle and a bottom ring is fastened non-rotatably in or on the tower. The bottom ring has a non-rotatable guide along the longitudinal axis of the tower.
