Abstract

Disclosed herein is an electrical insulating oil composition using a high-boiling-point aromatic fraction. The oil composition comprises a component having a distillation range of 280-330 DEG C, obtained by continuously distilling an aromatic hydrocarbon fraction from a platforming or aromatizing process. According to the disclosed invention, an electrical insulating oil composition having excellent voltage-withstand capability and excellent gas absorption capability can be obtained from an aromatic fraction. Also, the electrical insulating oil contains no unstable components, resulting in an increase in electrical properties, and thus has advantages of high stability and high potential gradient.
