This paper proposes double‐rod‐type jumper horns in strain assemblies with pipe jumpers for 500‐kV transmission lines, the structure of which is very simple. It can be estimated that no corona discharge appears on the horns under the line voltage of 525 kV. 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 60 ms against strong wind (10 m/s). The stable duration increases more than 300 ms under windless condition, therefore the horns have been adopted for practical use.
