Abstract (en)

[origin: EP2696358A1] The transformer has housings (200,201) inside which winding chambers (1-3) provided with primary and secondary windings (31,32) are arranged. The winding chambers are filled with an insulating fluid (87-91), and the housings are partially filled with insulating fluid so that the windings are surrounded by insulating fluid. The winding chambers are closed and separated from one another by using insulating partition wall (5,6). Isolation barriers made of solid insulation is formed within the housing for dividing the insulating fluid.
