FIELD: electricity.
SUBSTANCE: high-voltage bushing, comprising a hollow insulator and a conductor, stretching via the hollow insulator and including a hollow conductor (1), fixed on the ends of the hollow insulator and not supported by the insulator between fixed ends, the conductor (1) comprises a supporting part (2), located inside the hollow conductor (1), besides, the supporting part (2) stretches in longitudinal direction of the hollow conductor (1), and the supporting part (2) is made as capable of supporting the hollow conductor (1), in order to increase conductor stiffness and thus reduce the static deformation of the conductor in the hollow insulator, at the same time the high-voltage bushing is a bushing with gas insulation.
EFFECT: invention provides for reduced deformation of a conductor and prevention of insulation breakthrough in very long bushings.
