Experimental study for the spacer damper clamp displacement due to subspan oscillations

가공선로 서브스판진동이 스페이서댐퍼 클램프 변위에 미치는 영향 실험적 고찰

In order to protect conductors from oscillations or vibrations due to winds, spacer dampers or spacers are installed on bundled conductors in overhead transmission lines. Generally the spacer damper clamp can move slightly according to oscillation directions, namely conductor direction, vertical & horizontal direction This is for reducing fatigue phenomena of the clamps. Sometimes movement of the clamp to conductor direction raises a doubt for its necessity. Then this paper carried out oscillation tests to know clamp displacement due to the subspan oscillation.
