The MOD2 Spacer Damper controls galloping by the twisting mechanism in the clamps. The installation methodology is also a key factor in controlling high-amplitude galloping.
When the conductor experiences high-frequency vibration, the conductor moves against the clamp. The clamp itself creates an impact with the steel hoop, thereby absorbing the transferred energy.
This motion then creates movement of the coil springs, which also impacts the hoop, adding more energy dissipation.
