Abstract
A power capacitor including at least one capacitive winding, of self-healing type, located in a case made of plastic material and coated in a polymerizable resin cast directly into the case. The capacitor includes a breaking device sensitive to an overpressure. Passage of gases in the direction of the breaking device is achieved by deformation of the plastic material constituting the case. The plastic material of the case presents predetermined mechanical strength, impact strength and thermal resistance characteristics.
