High voltage overhead line pole high span larger role when the wire is subjected to wind, vibration will occur. When the wire vibration, working conditions at the most disadvantaged wire suspension. Due to multiple vibration can lead to fatigue due to cyclical bending failure occurs. When the overhead line span over 120 meters, the general shock hammer shock. In the high-voltage overhead line, on both sides of the wire near the insulators often linked to a hammer, this hammer called damper, in order to reduce wire vibration due to wind shame since established. High voltage overhead line pole high span larger role when the wire is subjected to wind, vibration will occur. When the wire vibration, working conditions at the most disadvantaged wire suspension. Due to multiple vibration can lead to fatigue due to cyclical bending failure occurs. When the overhead line span over 120 meters, the general vibration damper. For steel core aluminum, shockproof hammer weight w = 0.4d-2.2 (kg) where d-- wire diameter (mm) installation efficiency check shockproof hammer installation location should be determined in accordance with construction requirements. Earthquake hammer after installation, which can produce the opposite phase with the wire vibration motion, so that the wire vibration to eliminate or weaken. 3 development in recent years, from Europe to the introduction of a non-Bolt Damper - Preformed damper, completely avoiding the drawbacks caused by the use of bolts. And later by Preformed Damper Damper evolved a series of non-bolt structure, such as the hippocampus Slip damper, snagging Damper so swept the country, but have benefited from the preformed structure basis.
