Abstract :
In this paper, a new organic three-layer A (carbon black semi-conductive master batch and PE)-B (polyethylene)-A insulation structure was proposed and prepared to improve the performance of vacuum surface flashover by adjusting the permittivity of the A layer dielectric. It is proved that the three-layer insulation structure could greatly improve the vacuum surface flashover performance.
