ABSTRACT:
A transformer winding, made as a layered winding with striplike conductor insulated with at least one strip of insulation folded about the conductor, and a process for making the same, are disclosed. To make possible a fully automatic manufacture of the winding with sufficient mechanical strength and uniform impregnation, the insulation strip, in addition to insulation of the conductor, constitutes likewise the insulation of the layers. At the periphery of a winding layer there are punctate bonding places at predetermined distances only on the outside of the conductor insulation. The cross section of the layered winding may be essentially trapezoidal with the transition to the free outer end comprising one or more circular arcs with different radii.
