Composite conductor for transformer coil

The utility model discloses a composite conductor for a transformer coil, which comprises a plurality of conductors combined as one and an insulating layer covering the conductors, wherein, an insulating paper layer is arranged between two adjacent conductors, the insulating paper layer is 0.16 mm thickness, and the insulating layer covering the conductors is 0.675 mm thickness. Compared with the prior art method of covering each conductor with an insulating layer before combining individual insulating layers together, the utility model has the advantage that the insulating paper layer is arranged between the two adjacent conductors, that is, adopting the method of combining a plurality of naked conductors into a group of conductors connected in parallel, arranging an insulating paper layer between every two adjacent conductors, and then covering the group of conductors as a whole with a qualified insulating layer, thereby greatly reducing the overall size of the group of conductors as a whole and reducing th
