Description of the Invention: [Technical Field of the Invention] The present invention relates to a composition for an insulating oil containing an ester of a fatty acid. [Prior Art] The insulating oil is an insulating material which is insulated by electrical equipment such as a transformer, a circuit breaker, a capacitor, and the like, and generates heat. Since this insulating oil is used for a long period of time, a polychlorinated biphenyl (polychlorinated biphenyl) which is excellent in incombustibility has been widely used. Non-combustibility is a property that is necessary to suppress the risk of fire or explosion damage when electrical faults occur in the machine. However, from the viewpoint of environmental protection, it has been found that PCBs are harmful to the environment, so mineral oil or the like is used instead of PCB. In recent years, in terms of biodegradability and stability, it has also been studied to use as a lubricating oil component. A multi-fermented fatty acid ester, a vegetable oil, etc. (for example, refer patent document 1 and patent document 2). On the other hand, a fatty acid ester containing a fatty acid represented by a pine oil fatty acid has been used as a formulation component of a resin, an additive for fuel (for example, refer to Patent Document 3), and an oily agent (additive) of a lubricating oil (for example). , refer to Patent Document 4). These fatty acid esters are used as additives only in small amounts as described above, and are not used under severe conditions, such as those required for lubricating oil main agents, and the use of pine oil fatty acid esters as hydraulic oils is also reported ( For example, 'refer to Patent Document 5).
