Abstract |
In order to protect conductors from oscillations or vibrations due to winds, spacer dampers are installed on overhead transmission lines. Generally the spacer damper clamp can move slightly according to oscillation directions, namely in longitudinal, vertical & horizontal directions. This is for reducing fatigue phenomena of the conductor. But the high longitudinal- displacement of the clamp raises a doubt for its necessity. Then this paper carried out oscillation tests by using 4 bundle test lines, to know the relation between longitudinal displacement and oscillation. and suggests design necessity of the longitudinal articulation part for spacer damper clamps. |
