Abstract:
A folded insulated foil conductor for distribution transformers comprising:a length of sheet insulation material bonded to a corresponding length of foil conductor material to provide a length of flat composite foil conductor/insulation, the length of composite conductor/insulation being folded longitudinally into a substantially U-shaped length having horizontal portion between two leg portions with each leg portion having a free end, an un-insulated filler foil conductor strip disposed centrally in said folded insulated foil conductor and the leg portions of the U-shaped length of composite foil conductor/insulation being folded inwardly to a position substantially parallel to the horizontal central portion of the U-shaped length of composite foil conductor/insulation to bring the free ends of the leg portions into opposing relation to provide a folded insulated foil conductor having two conductor thickness surrounded by insulation, said un-insulated filler foil conductor strip increasing the conductor cross-sectional area of the folded insulated foil conductor.
