EXPLOSION-PROOF PORCELAIN HOUSINGS FOR GAS-FILLED INSULATING APPARATUSES AND PROCESS FOR PRODUCING SUCH PORCELAIN HOUSINGS

摘要

An explosion-proof porcelain housing for use in a gas-filled insulating apparatus,comprises an porcelain housing body, and a first and second films. The first film is made of a first insulating material having low hardness and high elasticity, and is bonded to an inner surface of the porcelain housing body. The second film is made of a second insulating material having high hardness and high mechanical strength, and is bonded to an inner surface of the first film. A process for producing such an explosion-proof porcelain housing is also disclosed.
