Abstract
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.
