ABSTRACT:
A wind turbine includes a tower; a blade for rotating on the tower; a rotor shaft, connected to the blade, having an axial hole; a line, arranged in the hole, for carrying a signal; a support, wrapped around the line inside the hole, for spacing the line from the rotor shaft inside the hole; where the support expands radially to at least partially fill an annular space between the line and an inside wall of the axial hole.
