ABSTRACT:
The invention concerns a spacer-damper of the type for separating bundled subconductors of a power transmission line and for damping vibrations generated in those subconductors. The spacer-damper comprises a metallic frame around which a plurality of arms are mounted, each arm having one extremity designed so as to receive one of the subconductors and another extermity connected to the frame by means of a joint. Each joint includes a ring fitting in a cheek, four shoulders radially and symmetrically mounted on the inner wall of the ring, four pairs of elastomers inside each ring and making a right angle with respect to one anther, the elastomer of each pair being spaced from one another by one of the shoulders, and a central pivot inserted between the pairs of elastomers and inside the ring. The ring and the cheek constituting each joint are maintained together by means of tenon-mortise joints and a set of bolts and nuts. On the other hand, the ring of the joint may be an integral part of either the frame or the arm, the associated cheek being then integral to the arm or the frame, respectively. Furthermore, there is provided an arrangement of a spacer-damper made of biarticulated arms including two orthogonally mounted parts.
