Abstract
A protective apparatus for a distribution line conductor includes an elongate tube configured to be installed on the conductor and a plurality of annular members concentrically positioned on the tube and configured to rotate independently of each other. The tube has a longitudinal axis and defines a longitudinally extending chamber configured to receive the conductor. The tube has opposite first and second ends and a longitudinally extending opening from the first end to the second end that facilitates installation of the elongate tube on the conductor. Each annular member includes an outer surface and a plurality of circumferentially-spaced apart members extending outwardly from the outer surface. Each annular member includes a longitudinally extending slot that is configured to align with the longitudinally extending opening of the tube to facilitate installation of the elongate tube and the plurality of annular members as an assembly on the conductor.
