Design method and application on the jumper-horn of the 765 kV prefabricated jumper device

765 kV 조립식점퍼장치의 점퍼혼 설계기법 및 적용방안

765kv Transmission lines of the contaminated areas need many insulators due to the contamination. So the length of the arcing hem is very long. Because it is very difficult to install the arcing hem on insulator string sets due to its length, we must install the arcing horn on the jumping devices, and studied about the jumper horn. This paper described the investigation and analysis of the installation status of the arcing horn, and the design of the jumper horn for 765 kV transmission lines.
