The main insulation of RIP bushing is the resin-impregnated paper capacitor core, which is alternately wound on the conductive pipe (rod) with insulating paper and aluminum foil according to the design requirements, impregnated with epoxy resin mixture under vacuum and cured at high temperature. The capacitor core is sealed and assembled into the dry type RIP bushing through the connecting flange and porcelain sleeve (or composite hollow insulator).This kind of casing truly realizes dry and oil-free. Since its invention in 1960, it has been widely used in Europe, America, Japan and other countries with its unparalleled advantages of OIP bushing. The company fully introduces talents with many years of manufacturing experience and German automatic manufacturing equipment to realize the high-quality production.
