電防止構造。In an insulated conductor having a conductor to which a high voltage is applied and a main insulating layer surrounding the conductor, from one end of a low-resistance corona shield layer applied to the main insulating layer, the Electric field relaxation paints having different control electric field values are sequentially applied onto the main insulating layer with one end of the side contacting the low-resistance corona shield layer aligned, and the electric field relaxation paint with a smaller control electric field value has a lower control electric field value. The electric field relieving paint having a large control electric field value is applied in a lower layer than the electric field relieving paint having a large control electric field value, and the length over which the electric field relieving paint having a small control electric field value is applied is shorter than the length over which the electric field relieving paint having a large control electric field value is applied.
