FIELD: electricity.
SUBSTANCE: invention is related to high-voltage engineering and, in particular, to high-voltage bushing insulators to ensure electrical insulation of conductor. The invention develops the electric bushing insulator which contains at least, two sheets of conductive foil placed concentrically around the conductor seat; and at least one FGM-part made of the material intended for field balancing and at least part of the edge (205/405) of the conductive foil sheet, at least partially elongated; the FGM-part and conductive foil sheet at which extension the FGM-part is placed are in electric contact with each other.
EFFECT: invention allows manufacturing of a bushing insulator having high ratio of voltage resistance and diameter of the bushing insulator.
