Abstract
A biodegradable soybean oil based electrically insulating fluid. The base oil is hydrogenated to produce maximum possible stability of the soybean oil, and can be winterized to remove crystallized fats and improve the pour point of the base oil without the necessity of heating the oil. The base oil can also be combined with an additive package containing materials specifically designed for improved pour point, improved cooling properties, and improved dielectric stability.
