  • Manufacturing process of a capacitor with delayed ageing and a capacitor manufactured according to this process
    Patent number: 5392190
    Abstract: The manufacturing process of a capacitor with a polypropylene dielectric film by introducing pre-cross-linking elements of the polypropylene at the time of manufacturing. When the capacitor is used, the electrical field and/or temperature generated trigger the cross-linking process of the polypropylene, delaying and slowing down the ageing phenomena, i.e. the decrease of the dielectric strength. The pre-cross-linking agent is a polyfunctional monomer to which an activation accelerator and/or a stabilizing agent can be added.
