Abstract: This invention relates to a lightning current transfer system adapted for usage in a wind turbine (W) having a hub (40) rotatably supported relative to a nacelle (50) and a plurality of pitchable blades (20) connected with the hub (20). The system (100) comprises a blade band (10) mountable to the root of the blade (10) and a lightning ring (30) mountable to the nacelle (50). The lightning ring (30) and the blade band (10) are positioned relative to each other to form a spark gap (SG) there between.
