Abstract
A damper for an overhead transmission line comprising a torsional bar disposed in a spaced and parallel arrangement with conductor means of an overhead transmission line; a fixture spacer to fix one of the ends of said torsional bar to said conductor means of the overhead transmission line; at least one bearing spacer to bear the other end of said torsional bar on said conductor means of said overhead transmission line so that said torsional bar is allowed to be twisted; and a pair of weights having an equal inertia moment and secured to said torsional bar adjacent to the torsional end and on either side thereof.
