<p>1368656 Capacitors ROBERT BOSCH GmbH 24 Feb 1972 [26 Feb 1971] 8524/72 Heading H1M In an impregnated capacitor wherein the dielectric consists of paper strips and optionally synthetic resin strips, at least one paper strip has an average surface roughness on both sides of at least 10% of its nominal thickness, a a raw density of from 1À20 to 1À31 g./cc., a thickness of from 8 to 20 microns and a dielectric strength of at least 100 kV/mm. The capacitor electrodes may be metallized self-healing coatings on the paper strips, or self-supporting metal strips. The capacitor may be of the wound type, and impregnated at 100 to 120‹ C. with an impregnant which swells the synthetic resin foils.</p> |
