A new kind of anti-dance fittings is composed of vibration-reducing and anti-dance damping spring interphase spacers to absorb the vibration energy of the wire through a spring, rubber and heavy ball system. The wire fatigue vibration test system platform is used to conduct the galloping tests of two phase six bundled wires installed with the ordinary interphase spacer and the vibration-reducing and anti-dance damping spring interphase spacer. The wire's vertical and horizontal displacements are measured against time after the movement becomes stable. It is concluded that the displacement of the wire is smaller when it is installed with the vibration-reducing and anti-dance damping spring interphase spacer under the same conditions and that the vibration-reducing and anti-dance damping spring interphase spacer has a better anti-dance performance and is a very practical anti-dance hardware, which can be applied in the transmission line.
