The Influence of Spacer Dynamic Properties in the Control of Bundle Conductor Motion

This paper presents the results of a field investigation on systems of either damping or non-damping articulated spacers with regards to aeolian vibrations, wake-induced oscillations and rain vibrations. Each test out of a program of five was systematically carried out on a comparative basis at the Magdalen Islands test line. It is shown that a low stiffness is desirable in spacer-dampers but that damping capacity is not a must for the attenuation of subspan oscillation.
