1. A method for winding a foil coil of a stereoscopic wound iron core transformer, comprising:
providing a stereoscopic wound iron core, wherein the stereoscopic wound iron core comprises a plurality of iron core posts;
providing an insulating layer, wherein the insulating layer is arranged on an outer wall of each of the iron core posts;
providing a plurality of cylinders, wherein a foil conductor, an interlayer insulator and an end insulator are respectively wound on the plurality of cylinders;
sleeving a rotating assembly outside the insulating layer;
arranging the plurality of cylinders on the rotating assembly;
fixing one end of each of the foil conductor, the interlayer insulator and the end insulator on the insulating layer;
arranging an inner leading wire portion at one end of the foil conductor connected with the insulating layer;
connecting and starting a driving device, wherein the driving device drives the rotating assembly to rotate, so as to drive the plurality of cylinders to rotate around the respective of the iron core posts, and the foil conductor, the interlayer insulator and the end insulator are all wound on an outer wall of the insulating layer with the respective of the iron core post as a central axis to form a coil body; and
arranging an outer leading wire portion at one end of the foil conductor far away from the inner leading wire portion.
