Abstract
A wind turbine having a wind turbine tower with a nacelle provided on the top to which a rotor hub with one or more wind turbine blades is rotatable mounted. A cable twisting system is arranged inside the wind turbine tower and suspended from the bottom of the nacelle. The cable twisting system comprises a number of cable spacing plates having a number of guiding means for guiding the electrical cables from the nacelle to the bottom of the wind turbine tower. A first and second element having engaging fingers configured to be brought into contact with each other are coupled to two adjacent cable spacing plates. The first element rotates relative to the second element when the nacelle is yawing, bringing the fingers into contact with each other. The two elements then rotate together as the nacelle continues to yaw in the same direction.
