Electric Field Simulation Study of Squeezed Insulated Tube Bus

In recent years, insulated tubular busbar have been widely used in power systems due to their excellent electrical performance. However, due to the fact that insulated tubular busbars have not yet established uniform industry specifications, product quality is uneven. In this paper, the squeezing insulation tube is taken as the research object. Based on the finite element method, the electric field distribution of the insulated tubular busbars under the eccentricity of insulation is analyzed. At the same time, the electric field distribution of the elbow at different bending radius is studied.
