FIELD: electricity.
SUBSTANCE: bushing comprises an electric conductor, a dielectric layer and a fastening unit. The layer of dielectric is made using elastic dielectric material and is placed between an electric conductor and a fastening unit. The fastening unit comprises at least one element to compress the dielectric layer, besides, the thickness of the dielectric layer between the compressing element and the electric conductor is less than the thickness of the dielectric layer in this area measured at lowest operating temperature after removal of the compressing element.
EFFECT: invention provides for mechanical strength and tightness during operation in wide range of working temperatures.
