Owing to its complex structure, high electric field strength, the rigid jumper on 1000kV double circuit tension tower is prone to corona that needs suppression and much more consideration. Using three dimensional finite element method software ANSYS, the electric field distribution on the surface of rigid jumper with aluminum tube structure was calculated when considering the effect of tower, fittings,...
Silicone rubber makes composite insulators show excellent moisture dirt performance because of its hydrophobicity. In the wet environment, separated water droplets instead of continuous water film will form on the surface of composite insulators, helping curb the occurrence of arc in high-strength field. However, separated water droplets will distort the electric field easily leading to the partial...
