FIELD: electricity.
SUBSTANCE: vacuum breaker (1) comprises a sealed chamber (4) with a cylindrical body (5), two electrical contacts (7, 7') and a dielectric coating (12) which covers the outer surface of the chamber (4). This coating (12) comprises at least two layers, namely a top layer (14) made of a synthetic material and an intermediate layer (13), which represents a continuous layer made of an organosilicon compound. The top layer (14) is located on the intermediate layer (13). The intermediate layer (13) is made discontinuous and localized on the metal sections of the chamber (4) for covering, at least partially, the outer surface of the metal sections. The organosilicon compound of the intermediate layer (13) comprises hollow bodies that are compressible, and also have a sheath made of a thermoplastic material.
EFFECT: increased reliability and simplified manufacturing method.
