1. A method for manufacturing an offshore wind turbine, the wind turbine comprising a high voltage cable configured to connect a generator of the wind turbine with a switch gear of the wind turbine, the method comprising:
a) assembling a tower of the wind turbine from several tower sections and guiding the high voltage cable inside the assembled tower from an uppermost platform of the tower to a lower part of the tower, the lower part being the lowermost platform of the tower or a part below the lowermost platform of the tower,
b) returning the high voltage cable at the lower part of the tower up again,
c) transporting the assembled tower to an offshore wind harvesting site by means of a vessel,
d) arranging the tower on a transition piece of the wind turbine, the transition piece being connected to a foundation of the wind turbine,
e) lowering the high voltage cable into the transition piece and towards the switch gear in the transition piece,
f) hoisting a lower part of the high voltage cable into a tray of a support structure, the support structure being located on a switch gear footbridge, and
g) adjusting an inclination of the tray to a length of the high voltage cable.
