Galloping of high voltage electric cables is one of serious problems during witer time. Since ice block along the cable works like wing for lift under the strong wind, self-excited vibration will be caused into galloping of cables. To lower the cost for electric transportation, researching for dumping method for galloping phenomena is important subjects. In this study we propose zaile method, connecting flux of cables with insulator chains, to lower vibration of cables. Models experiments for dumping effect of galloping have been done, with several zaile patterns. From the results, to reduce vibration, connection in vertical direction is the most effective one. Since with the zaile connection, vibration dumping was five times smaller than free galloping, it has been proved that zaile method is effective to reduce galloping vibration.
