摘要：
An improved electrical insulating oil and oil-filled electrical appliances impregnated therewith. The electrical insulating oil is quite suitable for use in oil-filled electrical appliances in which insulating materials or dielectric materials made of plastics are employed. The electrical insulating oil comprises (a) an electrical insulating oil except polyaromatic hydrocarbons and (b) an aromatic monoolefin and/or diolefin having two condensed or noncondensed aromatic nuclei.
