Abstract

The present invention relates to a spacer damper capable of absorbing vibrations. A technical gist of the present invention relates to a spacer damper for distancing a plurality of wires concentrated. More specifically, the plurality of wires distanced from each other by the spacer damper are stressed by being continuously shaken or vibrated by wind, earthquakes, or ambient noise. Clamp bodies for fixing the wires so that the spacer damper is not damaged even by such stress absorb shaking or vibrations by the elasticity of elastic springs, thereby extending the life of the spacer damper. A central weight containing a viscous liquid is fixed by a plurality of anti-vibration springs in a central hole of the spacer damper. Therefore, even when the spacer damper is shaken, the elasticity of the anti-vibration springs or the viscous liquid such as gel or oil minimizes ambient shaking or vibrations applied to the spacer damper.
