Power line protective apparatus having rotatable members

A protective apparatus for a distribution line conductor, the apparatus comprising:

• an elongate tube comprising opposite first and second ends, wherein the tube has a longitudinal axis and defines a longitudinally extending chamber configured to receive the conductor, wherein the tube comprises a longitudinally extending opening from the first end to the second end;
• a plurality of annular members concentrically positioned on the tube and configured to independently rotate about the longitudinal axis, wherein each annular member comprises an outer surface and a plurality of circumferentially-spaced apart members extending outwardly from the outer surface, and wherein each annular member comprises a longitudinally extending slot;
• and
• first and second flanges at the first and second ends of the tube respectively, wherein the flanges are configured to prevent the plurality of annular members from dislodging from the tube, wherein the first and second flanges each comprise a slot, wherein the slots of the first and second flanges and the slots of the respective annular members are configured to align with the longitudinally extending opening of the tube to facilitate installation of the elongate tube, the plurality of annular members, and the first and second flanges as an assembly on the conductor.
