It is shown that both (Strouhal) frequency and amplitudes of aeolian vibrations are practically unaffected by the component of wind velocity parallel to the conductor. While increased wind turbulence appears to attenuate vibration amplitudes, higher conductor tension has been shown to exacerbate conductor sensitivity to vibrations. Examples of the low aeolian-vibration response of bundled conductors equipped with damping spacers are reported and discussed. Wake-induced oscillations of bundled conductors are first investigated regarding constituent modes and frequencies. The severity of oscillations is then dealt with by means of an instability index which is used to reveal dependency upon wind velocity and angle of incidence, conductor tension and spacing-to-diameter ratio, bundle configuration and tilt angle as well as damping spacer type and number.
