A spacer jig using as a tool has developed for easily replacing the spacer dampers on the overhead power lines during the maintenance and repair. The spacer jig is comprised of: a frame having a polygonal shape of two flat panels in parallel with a clearance for mounting the fixtures arranged even intervals in the radial direction between the two flat panels; the frame having square shape using for four-conductor and hexagonal shape using for six-conductor overhead power lines; the fixtures consisting of stationary hexahedron nuts and rotational hexahedron nuts; a clamping arm forming cylindrical-shaped long shafts with threaded end portion for inserting into the fixtures; a cable gripping unit consisting of a clamp, lid, snapping latch and locking detent for easily opening and closing the lid to grip or release the cables, and a clamp mounting unit for rotationally mounting the cable gripping unit on top of the clamping arm.

A device for damping vibrations of an overhead conductor comprises a die cast weight and housing comprised of opposed weight and housing halves located on opposed sides of a clamp arm and having spherical outer surfaces to minimize corona and tooling costs. The clamp arm is located between two tubular elastomer damping elements secured in place between the clamp arm and the weight and housing halves. The damping device, in addition, includes a pin that secures the weight and housing halves, clamp arm, and damping members together in a sandwich-like construction.

A vibration absorber for attachment to a single conductor suspended transmission line to suppress vertical aeolian vibrations. A clamp arm has one end attached to a suspended cable and another end rotatably coupled to a housing having a weight extending therefrom through two frictionally-engaged elements which provide coulomb friction when the clamp arm is caused to rotate relative to the housing as a result of said vibrations. A separate resilient member couples the clamp arm to the housing to restore the initial orientation of the clamp arm.

A vibration absorber for attachment to suspended cables such as electrical transmission lines, to suppress vertical aeolian vibrations as well as horizontal subconductor oscillations. A clamp arm has one end attached to a suspended cable and another end rotatably coupled to a frame through two frictionally-engaged elements which provide coulomb friction when the clamp arm is caused to rotate relative to the frame as a result of said vibrations or oscillations. A separate resilient member couples the clamp arm to the frame to restore the initial orientation of the clamp arm.

A vibration absorber for attachment to suspended cables such as electrical transmission lines, to suppress vertical aeolian vibrations as well as horizontal subconductor oscillations. A clamp arm has one end attached to a suspended cable and a fulcrum adjacent the other end. The fulcrum is rotatably coupled to a frame, and the end of the clamp arm adjacent the fulcrum is coupled to the frame through two bellows elements which force air through small orifices to provide viscous friction when the clamp arm is caused to rotate relative to the frame as a result of said vibrations or oscillations. Each bellows includes a resilient pleated portion which acts to restore the initial orientation of the clamp arm.

A pendulum type vibration absorber tester/adjuster, which enables vibration absorbers to be set to a desired damping in the factory. The test/adjustment is effected by mathematically determining the pendulum weight and arm length, setting the pendulum into motion and recording the motion on a chart recorder, and adjusting the damping of the absorber until a predetermined decrement is obtained.

A conductor support member includes an external surface having a first portion thereon. The first portion is shaped to generate a localized increase in voltage gradient. Shielding means including surfaces intersecting to define a sharp edge are provided to promote a negative corona discharge adjacent the first portion. The said negative corona discharge produces a positive space charge to reduce the voltage gradient at the first portion. This inhibits the generation of positive corona discharge.
