ABSTRACT:
An electrical induction device for high voltage applications, of the type comprising a magnetic core which has at least one leg and is operatively coupled to a supporting structure, at least one inner winding which is arranged around said leg and has a first rated voltage, at least one outer winding which is arranged around said at least one inner winding and has a second rated voltage; and electrically insulating means, wherein said at least one inner winding comprises a plurality of substantially concentric turns formed by a sheet of electrically conducting material which is spirally wound, and in that said electrically insulating means comprise at least one layer of electrically insulating material which is arranged between mutually facing surfaces of said concentric turns, and first shaped insulating means which edge, at least partially, at least one of the upper and lower external rims of said inner winding.
