Zusammenfassung:	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. L'invention concerne un fluide diélectrique thermiquement stable. Le fluide diélectrique comprend (a) une huile, (b) un anti-oxydant de type phénol encombré, substitué, ayant au moins deux groupes crésol substitués qui sont liés de manière covalente l'un à l'autre par un pont méthylène, et (c) un anti-oxydant de type diphényl amine substituée, ayant au moins deux groupes phényle substitués qui sont liés de manière covalente l'un à l'autre par un pont amine.
