Abstract
A device for spacing overhead, parallel subconductors of a conductor bundle and for damping vibrations of the subconductors. The device comprises rigid, elongated arms pivotally connected together at one end of each arm and having a clamp at the other end of each arm for attaching the arms to respective subconductors. A resilient, viscoelastic pad or disc is disposed between the arms in opposed recesses provided in the arms at the location at which the arms are pivotally connected together, the pad or disc providing the primary damping mechanism for the device.
Claims8
A lightweight, inexpensive frameless damper spacer for parallel, overhead conductors comprising at least two, rigid, spacer arms, rigid pin means pivotally connecting the arms together adjacent a central location of the spacer, means at the end of each arm remote from said central location for clamping each of the arms to a respective overhead conductor, opposed recesses provided respectively in the arms adjacent said central location, a relatively thick, resilient viscoelastic disc located and secured between said arms and in said recesses, the opposed recesses and disc having matching configurations that function to hold the viscoelastic disc against relative rotation with respect to the arms when relative rotation of the arms occurs about said rigid pin means.
