This paper proposes a new compound mode composed of a composite insulator in series with glass insulators, designed to improve its electric field distribution based on its own capacitive electric field distribution characteristics. A three-dimensional electric field calculation model of a composite insulator in a transmission line was designed and employed to study the improved situation of the surface potential and the electric field distribution of a composite insulator, with a glass insulator installed in its high-voltage side at 110 kV.
