    Abstract: An articulated spacer damper for transmission line cables is disclosed comprising a frame, a plurality of intermediate arms each resiliently pivotally connected at one end to the frame and at its other end to the proximal end of a clamping arm, the distal end of which is provided with clamping means for respectively grasping individual conductors. Each of the pivotal connections includes a pair of spaced resilient energy absorbing elements having non-circular cross section which are interposed between the respective components and lockingly engaged with recesses formed in each component. The components are clamped together by a locking bolt extending through the elements and defining an axis of hinged part rotation while holding the elements in compression.
