MOLD FOR IMPREGNATING A PREFABRICATED CONDENSER CORE OF A HIGH-VOLTAGE BUSHING AND DEVICE FOR FORMING A CONDENSER CORE OF A HIGH-VOLTAGE BUSHING

摘要

The mold (10) is used for impregnating a prefabricated condenser core (C) of a high voltage bushing with a liquid resin and comprises two mold modules (11, 12, 13, 11 a, 11 b) movable against each other and shaped to form an axially symmetric mold cavity (14). The mold (10) forms a column of cylindrical design, in which the at least two mold modules are arranged on top of each other. A first (12) of the two mold modules is executed as hollow cylinder. Two opposing front faces (111, 121) of the two mold modules and a circular O-ring arranged between the two opposing front faces form a first sealing interface (S1) of the metal mold. Such a mold has a very efficient sealing system and allows 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 specific temperature profile.
