A method for winding a coil for a transformer comprising providing a cylindrical inner tube of insulating material including a radially outwardly projected first end wall section disposed at a first end of the cylindrical inner tube and a radially outwardly projecting second wall section disposed at a second end of the cylindrical inner tube; winding a first insulating layer onto the cylindrical inner tube so as to extend to the first end wall section and the second end wall section; and winding a first winding wire layer onto the first insulating layer so as to provide a first distance between a first end of the first winding wire layer and the first wall section and a second distance between a second end of the first winding layer and the second end wall section.

Method for producing a transformer coil, and a transformer coil produced using this method

A winding for a transformer or a coil having a ribbon electrical conductor and an insulating material layer composed of ribbon insulation material wound jointly to form turns around a winding core. The individual turns of the winding have a predetermined winding angle with respect to a winding axis of the winding core and are disposed such that they partially overlap one another. An insulating layer is inserted between two radially adjacent layers of the turns. Furthermore, a thickness of the insulating layer is locally matched to the voltage difference determined there. In addition, the thickness of the insulating layer is locally matched, the thickness being interchanged in sequence of the method A+B determined there, to the voltage difference between the two relevant radially adjacent layers at the relevant axial point.
