The spacer damper is generally installed in the middle of the span and installed at intervals of 50 - 60m. For the spacer dampers of two-conductor, four-conductor, six-conductor, and eight-conductor bundles, after installing the spacer damper on the bundled conductor and comparing with the vibration amplitude without the spacer damper, the vibration amplitude of the two-conductor bundle is reduced by 50%, and that of the four-conductor bundle is reduced by 87% and 90%.
