Abstract

PURPOSE: To heighten the dielectric strength of a supporting insulator, by making a cavity in the grounded part of the supporting insulator and coating electroconductive paint on the internal surface of the grounded part to set the same potential on the internal surface as a fixing side.
CONSTITUTION: The cavity 3 is provided in the grounded part of the supporting insulator. The electroconductive paint 4 is coated on the internal surface of the grounded part so that the same potential is set on the internal surface as the fixing side. The length l of coating of the paint 4 is made equal to 0 to 45% of the total length L of the supporting insulator 2. Thereby, the distribution of potential on the grounded part is improved and the dielectric strength is heightened.
