Abstract: The present invention relates to a lightning current transfer system (100) adapted for usage in a wind turbine (W) having a hub (20) that is rotatably supported relative to a generator in a nacelle (30) and a plurality of blades (10) that are pivotably connected with the hub, wherein the hub (20) is covered by a spinner (20A). The lightning current transfer system (100) comprises a blade band (10A) mountable to the root of the blade (10); a lightning ring (80) mountable to the spinner (20A) facing the nacelle (30); a first contact device (70) mountable to the spinner (20A) adapted for providing lightning current transfer from the blade band (10A); a connecting device (75) for connecting the first contact device (70) with the lightning ring (80); and a second contact device (30B) mountable to the nacelle (30) and adapted for providing lightning current transfer from the lightning ring (80) to ground.
