Disclosed is a base agent for electrical insulating oils, which mainly contains an esterified product of glycerin and a linear or branched, saturated or unsaturated fatty acid having 6-14, preferably 8-12 carbon atoms. This base agent for electrical insulating oils is excellent in electrical characteristics, oxidation stability, cooling characteristics, flame retardance and safety. In particular, this agent for electrical insulating oils can meet energy/environmental problems by using an edible oil and fat, which is obtained by using a fatty acid derived from a vegetable oil as a raw material, as the linear or branched, saturated or unsaturated fatty acid having 6-14 carbon atoms.

Base agent for electrical insulating oil

A base for electric insulating oil comprising an esterification product from a C-Chigher fatty acid and a C-Cbranched aliphatic monohydric alcohol; or a base for electric insulating oil comprising an esterification product from a mixed fatty acid derived from palm oil and/or mixed fatty acid derived from soybean oil and a C-Caliphatic monohydric alcohol or C-Cbranched aliphatic monohydric alcohol. The thus provided base for electric insulating oil excels in viscosity, fluidity, chemical stability, etc. and is capable of satisfactorily exhibiting electrical characteristics of electric insulating oil.

There are provided an electron beam application method and an electron beam application device capable of uniformly applying electron beams to an object even if the electron beams have a low energy. For this, electron beams (EB) are applied to a beverage container () (object) within a magnetic barrier (MF) formed by combining a plurality of magnetic fields generated in an electron beam application region.
