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.

Abstract: A spacer damper for transmission line cables is disclosed comprising a substantially planar frame and a plurality of clamping arms each resiliently pivotally connected at its proximal end to the frame and provided at its distal end with clamping means for respectively grasping individual conductors. The frame is of rigid one-piece construction and provided at each region of pivotal connection with a recessed portion into which at least the proximal end of the arm extends so as to lie substantially in the plane of the frame. A locking bolt fixed with respect to the frame and extending through the recessed portion and through the proximal end of the arm is provided to define an axis of hinged part rotation for the arm. Each arm is resiliently pivotally connected to the frame by a pair of spaced resilient energy absorbing elements located on either side of the arm to be traversed by the bolt and lockingly engaged with recesses formed in the arm.
