ABSTRACT:
A spacer damper for providing proper separation and effective vibration damping of subconductors includes a structural hoop about which clamps are positioned at equal intervals. The clamps allow attachment of the spacer damper to the subconductors and are separated by springs about the hoop and between the clamps. The hoop and subconductors are positioned substantially in the same plane to reduce corona effects. Additionally, a suspension clamp is securable to an insulator of a tower to support a subconductor.
