To develop a new type of nonflammable large-power transformer which uses perfluorocarbon liquid as the cooling and insulation medium, the basic cooling characteristics of the liquid were investigated. Using a horizontal coil duct model, design data on heat transfer characteristics of perfluorocarbon liquid were obtained by the computer program. Using a two-dimensional cooling model of nine coils per section, the velocity distribution in the coil ducts and the temperature rise distribution of the coils were clarified. Comparisons were made between experimental and calculated results, and the developed computer program was found to be valid for the prediction of the velocity distribution in the coil ducts and of the temperature rise distribution of the coils
