Abstract
A spacer-damper for overhead transmission lines of at least three subconductors comprising arms, one for each subconductor, mounted by resilient damping means to a rigid frame. Each arm has a cable clamp at one end and at least two of the arms extend from the frame so that a line between the clamp and the other end of the arm is in a direction generally perpendicular to a plane including the axis of the bundle and the center line of the subconductor engaged by the clamp.
