Abstract:
An insulating device includes a body portion including a first surface feature extending between a first surface end and a second surface end. The first surface end defines a first surface cross-sectional size. The second surface end defines a second surface cross-sectional size. The second surface cross-sectional size is less than the first surface cross-sectional size. The body portion includes a second surface feature extending between a third surface end and a fourth surface end. The third surface end defines a third surface cross-sectional size. The fourth surface end defines a fourth surface cross-sectional size. The fourth surface cross-sectional size is less than the third surface cross-sectional size. The insulating device includes a flange portion having a flange wall. The flange wall includes a first mating portion that engages the first surface feature and a second mating portion that engages the second surface feature of the body portion.

Abstract:
An exemplary mold is disclosed for impregnating a prefabricated condenser core (C) of a high voltage bushing with a liquid resin and includes two mold modules movable against each other and shaped to form an axially symmetric mold cavity. The mold forms a column of cylindrical design, in which the at least two mold modules are arranged on top of each other. A first of the two mold modules can be executed as a hollow cylinder. Two opposing front faces of the two mold modules and a circular O-ring arranged between the two opposing front faces form a first sealing interface of the metal mold. Such a mold can have a very efficient sealing system and allow high pressures to be applied to the liquid resin and a beneficial forming of the condenser core in a device in which the resin is cured according to a specified temperature profile.
