Overview

Each of conductors for long-distance & big-capacity super high voltage transmission lines are adopted two, four & more split wires. So far 220KV & 330KV transmission lines are equipped with two split wires while 500KV transmission lines are outfitted with three or four split wires; those super high voltage or ultrahigh voltage lines that higher than 500KV are matched with six & eight split wires. In order to keep the distance between the split conductor harnesses invariant for catering to the established electricity performance & reducing voltage gradient appeared on the surface so that the harnesses will not arouse electromagnetic force resulting in the interaction on short circuit, spacer is needed to be installed on the interval among different spans. Moreover the installation of spacer will be also helpful to remove the swing on span & aero vibration.
