METALLIZED PLASTIC FILM CAPACITOR

摘要

An MF capacitor of an oil impregnation type, whose durability in constant voltage application is so high that it is suitable for practical use. The metallized plastic film is impregnated with an electrically insulating oil composition obtained by adding 5-80% by weight of natural fatty acid triglyceride which contains a less amount of fatty acid ester having free hydroxyl radical to an aromatic hydrocarbon having a specific chemical structure and being liquid at -30.degree.C.
