Document Type and Number:
Japanese Patent JP3474216
Kind Code:
B2
Abstract:
PURPOSE: To facilitate manufacture and reduce the cost of a voltage bushing which is high in stability and insulating resistance by providing an insulating joint part of the vacuum electrical voltage bushing with a support body, provided with an enamel coating or a glass coating.
CONSTITUTION: Voltage bushings 15, 16 are formed by applying an enamel coating or a glass coating to support bodies made of ceramic or plastic and inserted in hole parts 13, 14 of a first conductive member 2 and a second conductive member 3. The support bodies can be manufactured easily into sizes and shapes at a low cost using ceramic, plastic, or the like, and the support body is provided with desired vacuum airtightness, heat resistance and strength by applying an enamel coating or a glass coating to the whole or part of the support body.
