1. A wind turbine comprising a stationary part including a tower (1) extending substantially vertically, a nacelle (2) comprising a wind rotor having at least one blade arranged on a main shaft having a substantially horizontal rotation axis and a power transmission system, a yawing system comprising a stationary part being fixed to an upper end of the tower (1) and a movable part being fixed to the nacelle (2), the stationary part and the movable part being designed so that the nacelle (2) is being supported vertically and horizontally by the tower (1) and may pivot relatively to the tower (1) about a substantially vertical yawing axis (A), and a plurality of elongated members such as bendable electrical power cables (9) for transferring electrical power from the generator system, the plurality of elongated members such as the power cables (9) being fastened at an upper end to the nacelle (2) and at a lower end to the stationary part of the wind turbine, and a passage (4) being defined between the nacelle (2) and the tower (1) and being positioned so that the vertical yawing axis (A) passes through the passage (4), the plurality of elongated members such as the electrical power cables (9) passing through the opening, said wind turbine further comprising at least a first suspension (5) being suspended by the nacelle (2), the first suspension defining substantially vertically extending supporting surfaces (15), the outer surface of each of said elongated member such as the electrical power cables (9) for a longitudinal length of at least four times the mean outer diameter (d1, d2) of the item being in abutting contact with and squeezed between at least two of each supporting surfaces (15) so that a substantial part of the weight of the member is supported by the first suspension (5).
