Abstract	The oscillation is very dangerous in bundled transmission lines, besides 4 bundle transmission lines are very weak for subspan oscillations. In some cases, subspan oscillations are continuously occurred in the same subspan. In order to develop the control method of the above subspan oscillation, this paper suggests a method of applying twin spacers to the subspans. We have carried out some tests to analyze the oscillation phenomena after installing twin spacers on 4 bundle overhead lines, and we got a good effect for controling subspan oscillations by installing twin spacers.
