CROSS-BAR FOR WIRES OF AERIAL POWER LINES Russian patent published in 1997 - IPC

FIELD: electrical power engineering, damping of parasitic vibrations of wires in aerial power lines. SUBSTANCE: cross-bar two members mounted for longitudinal movement of one member relative to other and elastic rest in the form of twisted cylindrical spring attached to wires with the aid of clamps mounted on its butts. Members are manufactured in the form of cylindrical permanent magnets magnetized in axial direction and facing each other with unlike poles. Magnets are arranged concentrically inside spring in its midpart, are attached to spring with external butts facing wires and have axial clearance between internal butts facing each other. EFFECT: enhanced reliability of cross-bar. 2 dwg
