Abstract
A rotor blade for a wind turbine comprises a rotor blade body with a root for connecting the rotor blade to a hub of a wind turbine, a tip, a leading edge and a trailing edge. The blade has a movable part, and motion transmitting means for connecting to an actuator being placed preferably outside the blade body, and transmitting motion from the actuator to the movable part. The motion transmitting means is electrically non-conductive, whereby the risk of lightning stroke accidents is reduced.
