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, ha, lib) movable against each other and shaped to form an axially symmetric mold cavity (14). T he 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 0-ring arranged between the two opposing front faces form a first sealing interface (Si) 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 condense r core in a device in which the resin is cured according to a specific temperature profile.
