Embodiment Construction

[0047] During the different stages of the power cable installation method according to an embodiment of the invention, the in- Figure 1 to Figure 3 A wind turbine tower 1 is schematically illustrated in FIG.

[0048] The wind turbine tower 1 comprises means 3 for installing power cables 5 in the wind turbine tower 1 . Thus, the device 3 comprises a support system 7 which, in Figure 4 , 5 and 6 are illustrated in more detail and will be explained below. The support system 7 is adapted to support a portion 9 of a cable section 5 within the tower 1, the cable section 5 having a length greater than the tower height h by an excess cable section 11 in the form of a tower Cable loop in frame 1 (includes sections 27 and 33, see Figure 4 ).

[0049] During the execution of the method of installing the power cable 5 in the wind turbine tower 1 , auxiliary hoisting ropes, not shown, have been attached to the first attachment area 13 , which can be connected to the cable 5 The en...

Abstract

Power cable installation in a wind turbine tower. It is described a method of installing a power cable (5) in a wind turbine tower (1), in particular for transportation, the method comprising: arranging a section (5) of the cable within the tower, the section having a length, in particular by at least an upper excess cable portion, greater than the tower height (h), by forming cable loops (27, 33) within the tower (1), wherein an angle enclosed between a normal (34) of a cable loop plane and the longitudinal direction (4) of the tower (1) is between 70 degrees and 110 degrees.

Description

technical field [0001] The present invention relates to a method and a device for installation of power cables in wind turbine towers, in particular for transport. Background technique [0002] In a nacelle mounted on top of a wind turbine tower, the wind turbine includes a generator that generates electrical energy when a rotor to which a plurality of rotor blades are attached rotates. Electrical output power is conveyed in power cables extending through the wind turbine tower and supplied to sea or underground cables that supply electrical energy to the utility grid. [0003] Conventionally, installation of high voltage (HV) power cables in wind turbine towers is performed at an assembly site, such as an assembly port prior to installation at an operating site, eg offshore. In conventional methods, the power cables are pulled from drums in the bottom of the tower by a crane arranged in the top of the wind turbine tower. [0004] In order to provide sufficient cable lengt...
