Abstract

1292819 Capacitors HIVOTRONIC Ltd 5 Aug 1970 [13 Aug 1969] 40421/69 Heading H1M A capacitor dielectric comprises a layer of plastics material, e.g. polypropylene or polycarbonate, impregnated with a mixture of an oil, e.g. a silicone oil, and a thickener, e.g. a gelling silicone, the mixture thickening or solidifying after impregnation. Multiple layers of the plastics material, optionally interleaved with paper layers, may be used.
