Abstract

Equipment for producing a high voltage rectifying unit wherein there is a resin ingredient tank and a curing agent tank for storing separately the resin ingredient and the curing agent, a closed mixer for mixing the resin ingredient and the curing agent, a vacuum chamber for injecting a mixed thermo-setting resin composition into the high voltage rectifying unit, a chamber for defoaming the injected resin composition, a furnace for curing the injected resin composition by heating, and a carrier apparatus covered to isolate the external atmosphere which may carry the resin composition-injected high voltage rectifying unit from the defoaming chamber to the curing furnace, whereby the procedures from vacuum injection to curing can be carried out continuously and automatically.
