Abstract: At least one wound film/foil or metalized film capacitor is sealed between its electrodes to form a sealed enclosed annular region between the interior of the enclosure, the electrodes and the exterior of the wound capacitor to form a sealed capacitor assembly. A fluid dielectric can be introduced into the sealed enclosed annular region under a vacuum to form a sealed and impregnated wound capacitor assembly.

Abstract: A capacitor assembly is formed from one or more capacitive elements placed between a pair of opposing brackets. Each bracket has at least one L-shaped section and an arcuate section. Each L-shaped section has a capacitor seating surface and an assembly connecting surface that is substantially perpendicular to the capacitor seating surface. The arcuate section is adjacent to the capacitor seating surface. The opposing ends of each capacitive element is in electrically contact with the capacitor seating surfaces on the opposing brackets. When secured to a bus bar by fasteners located in the regions formed by the arcuate sections of the opposing brackets the assembly connection surfaces serve as electrical and thermal conducting regions between the capacitor assembly and the bus bars. Alternatively a capacitor assembly may be secured to bus bars by fastening to the capacitor seating surfaces.
Abstract: A wound metalized film and metal foil capacitor with layers arranged and wound to provide internal parallel capacitors utilizing offsets between the internal spacings, or margins, of the metal electrodes. The arrangement permits more efficient heat transfer from the interior of the capacitor by the metal electrodes from internal regions that generate heat.
