Importance of the Spacer-Damper Installation in Overhead Lines
송전선로에서 Spacer-Damper 설치시공의 중요성
Abstract
Wind-induced oscillations are known to cause damage to the conductors and related hardware through fatigue, clashing of the bundled conductors and bolt loosening. Wake-induced oscillations have been known since the advent of bundled conductors. they are caused by aerodynamically unstable forces acting on the leeward conductors in the wake of the windward conductors, In order to control it, spacer dampers are installed in transmission lines with bundled conductors. Spacer damper installation is very important, it can cause damage to the conductors and spaer damper itself. This paper suggests importance of spacer damper installation in bundled conductor systems.
