Abstract
A spacer-damper for maintaining the spacing between electrical transmission conductors or the like and for damping any vibratory motion of such conductors includes a rigid spacer in the form of a multi-sided frame having at least two spherical mounts for conductor clamps. The clamps are connected to the spherical mounts, but separated therefrom by a resilient damping covering on the spherical mounts. Indentations on the spherical mounts and on the clamps mate with protrusions on inner and outer surfaces of the resilient damping covering to inhibit relative movement therebetween. Longitudinal, transverse and vertical vibrations in the conductors held by the clamps are damped by shear forces which arise within the resilient damping material, longitudinal vibrations being parallel to the ground axially along the length of the conductors, transverse vibrations being parallel to the ground but perpendicular to the conductors, and vertical vibrations being perpendicular to the ground.
