ABSTRACT:
An electric component, in particular an electric switch placed in a liquid-filled housing of an electrical installation, in particular a transformer, is filled with an insulating and cooling medium. The use of a compensating element, for example in the form of a bellow, makes it possible to transmit volume variations produced in the electric component directly to the surrounding liquid contained in the housing.
