Abstract
Provided is a method of installing a power cable in a wind turbine tower, in particular for transportation, the method including: arranging a section of the cable within the tower, the section having a length, in particular by at least an upper excess cable por-tion, greater than the tower height, by forming a cable loop within the tower, wherein an angle enclosed between a normal of a cable loop plane and the longitudinal direction of the tower is between 70° and 110°.

A method of installing a power cable in a wind turbine tower, the method comprising:
- arranging a section of the cable within the tower, the section having a length, greater than the tower height, by forming a cable loop within the tower, wherein an angle enclosed between a normal of a cable loop plane and the longitudinal direction of the tower is between 70° and 110°,
- wherein forming the cable loop comprises lowering another part of the cable through an opening in a platform to form a lower portion of the cable loop.
A wind turbine tower including an arrangement for installing a power cable in the wind turbine tower, the arrangement comprising:
- a support system attached to a platform within the tower and installed within the tower and adapted to support a section of a cable within the tower, the section having a length greater than the tower height by an excess cable portion, in a form of a cable loop within the tower, wherein an angle enclosed between a normal of a cable loop plane and the longitudinal direction of the tower is between 70° and 110°,
- wherein the platform has an opening allowing, for forming the cable loop, to lower another part of the cable through the opening in a platform to form a lower portion of the cable loop.
