摘要： A method of manufacturing an electrical device includes providing a composition comprising a mixture of vegetable oil fatty acid esters as a dielectric fluid in an electrical apparatus. The mixture of castor oil fatty acid methyl esters can contain the methyl stearate in a mass content of 1 to 20% to total amount of the mixture, the methyl oleate in a mass content of 1 to 90% to total amount of the mixture, the methyl linoleate in a mass content of 1 to 80% to total amount of the mixture, the methyl palmitate in a mass content of 1 to 50% to total amount of the mixture, the methyl ricinoleate in a mass content of 0 to 4% to total amount of the mixture, and the 10-undecylenic acid in a mass content of 0 to 1%.
