“fluido dielétrico, dispositivo elétrico e processo”. a divulgação é direcionada a um fluido dielétrico termicamente estável. o fluido dielétrico inclui (a) um óleo; (b) um antioxidante fenólico impedido, substituído tendo pelo menos dois grupos cresol substituídos estando covalentemente ligados entre sí por uma ponte de metileno, e (c) um antioxidante de difenil amina tendo pelo menos dois grupos fenila substituídos estando covalentemente ligados entre si por uma ponte de amina. The disclosure is directed to a thermally-stable dielectric fluid. The dielectric fluid includes (a) an oil, (b) a substituted, hindered phenolic antioxidant having at least two substituted cresol groups being covalently bonded to each other through a methylene bridge, and (c) a substituted, diphenyl amine antioxidant having at least two substituted phenyl groups being covalently bonded to each other through an amine bridge.
