PURPOSE:To alleviate the concentration of an electric field of an end by replacing the conductor of an end section with a conductor having different sectional shape only by one turn to form a twisted wire shield provided with an insulation coating layer. CONSTITUTION:In a core type transformer, low and high voltage windings 2, 3 are wound from inside in a core 1. The winding 2 is formed of a helical winding. The winding 2 is wound helically while forming a section 5 in a horizontal duct 6. One turn of the end of the winding 2 is reconnected with a twisted wire shield 7. The shield 7 is formed of a twisted wire 7a and an insulating coating layer 7b for coating the outside of the wire 7a. |
