Patent ID: 11624353

Abstract:
A new method for installing one or more electric cables (60) in a wind turbine tower section (100) is provided. The method comprises providing the wind turbine tower section (100) in a substantially horizontal orientation and installing a zip line (20) inside the wind turbine tower section (100), between a first end (120) and a second end (130) of the wind turbine tower section (100). The method further comprises coupling a second end of the electric cables (60) to the zip line (20) at a location near the first end of the wind turbine tower section (100), drawing the second end of the electric cables (60) through the wind turbine tower section (100) along the zip line (20), decoupling the second end of the electric cables (60) from the zip line (20), and removing the zip line (20) from the wind turbine tower section (100). The method further comprises anchoring a first end of the electric cables (60) to the wind turbine tower section (100), at a location adjacent the first end of the wind turbine tower section (100), and anchoring the second end of the electric cables (60) to the wind turbine tower section (100), at a location adjacent the second end of the wind turbine tower section (100).
