We have proposed the double rod type jumper horns in strain assemblles with pipe-jumpers for 500kV transmission lines, the structure of which are very simple. It can be estimated that no corona discharge appears on the horns under the line voltage of 525kV. The arc behavior on the double rod type jumper horns is similar to that on the single rod type horns. The arc can be held stably for 60ms against strong wind (10m/s). The stable duration increases more than 300ms under the windless condition. Therefore the horns have been adopted in practical use.
