る電気絶縁強度を有していなければならない。Cellulose paper, synthetic insulating paper, plastic film, or a combination of these is used to insulate the conductor portions of oil-filled electrical equipment. These insulating materials must have the electrical insulation strength required by electrical equipment as an oil-immersed insulation system combined with insulating oil.

と七が必要である。Conventionally, the above-mentioned cellulose-based kraft paper has been widely used for this type of oil-immersed insulation system. Currently, oil-immersed electrical equipment tends to have higher voltages and larger capacities, and therefore the design dimensions based on the insulation strength of conventional oil-immersed insulation systems have become enormous. For this reason, it is necessary to reduce the size of the equipment by increasing the insulation strength and reducing the insulation part or insulation interval.

。Therefore, the present invention provides an insulating material with superior electrical insulation strength compared to prior art oil-immersed insulation systems, thereby reducing the size of the insulation, the size of equipment, and manufacturing costs. The purpose is to reduce the insulating strength of the conventional oil-immersed insulation system by combining it with an inorganic insulating material. It has now been found that strength can be obtained.Thus, according to the present invention, electrical insulation strength is provided by combining an inorganic insulation with a conventional paper-like or film-like oil-immersed insulation system. l, 6 The oil-immersed insulation system whose electrical insulation strength is improved in the present invention may be any conventionally well-known insulation system, such as cellulose paper, synthetic paper, porous plastic film, etc., coated with insulating oil. You can give things that have been impregnated.
