HIGH-VOLTAGE BUSHING INSULATOR Russian patent published in 2006 - IPC H01B17/26 

FIELD: electrical engineering; basic components of electrical equipment.

SUBSTANCE: proposed bushing insulator that can be used for high-voltage metrological gas and vacuum capacitors has current-carrying stick with spherical bulge whose diameter amounts to 1.5 to 3 diameters of current-carrying stick, center of the latter being spaced ±1.5 diameters of this stick from supporting surface of flange. Insulator incorporates provision for eliminating unpredicted displacement of current-carrying stick relative to supporting surface of flange under impact of thermal deformations causing thermal expansion of its length.

EFFECT: enhanced operating reliability independent of temperature conditions.
