Four Bundled Spacer Damper

Spacer rod refers to a fitting installed on the split wires to fix the spacing between the split wires to prevent the wires from whipping each other and suppress the breeze vibration and secondary pitch vibration. Spacer bars are generally installed in the middle of the gear pitch, and installed at a distance of 50-60m[1]. Comparing the vibration amplitude of the two-split, four-split, six-split, and eight-split conductors with the split conductors, the vibration amplitude of the split conductors is reduced by 50% after the spacer rods are installed, and the four-split conductors are reduced by 87% and 90%.
