In the utility model, the flat type copper wire radical of forming the sub-thread transposed conductor is 19-45 (being a n=8-22) root, and the thickness of every copper strap wire is 1.1-2.0mm, and width is 4.5-9.mm.
In the utility model, press from both sides the electric insulation paperboard strip of filling up between two strands of transposed conductors, can be coincided by the layer 1-7 insulating paper and form, the thickness of every layer of insulating paper is 0.3-0.5mm.
The manufacture method of the combined shifting lead of the utility model design is as follows: technology is made the sub-thread transposed conductor routinely, two strands of transposed conductors are axially arranged side by side, the therebetween pad is made the electric insulation paperboard strip of shielding usefulness, and insulating barrier is twined in the outside, forms the first segment doublet cord; According to design length (for example 6690cm), at the first changeover portion place front end upside and list the 3rd strand of transposed conductor that is used to replace, also press from both sides pad electric insulation paperboard strip in the centre, in rear end, changeover portion place, cut off first sub-thread transposed conductor of downside, changeover portion is twined parcel with insulating paper, in simultaneously the head of line packet of upper and lower both sides transposed conductor being rolled in; Middle the 2nd transposed conductor with and the 3rd transposed conductor listing between continue the electric insulation base plate bar that the folder pad is made shielding usefulness, insulating barrier is twined in the outside, forms the 2nd and saves doublet cord, up to second changeover portion; And the like, to the last one saving doublet cord, whole combined shifting lead profile is stairstepping.
The combined shifting lead of the utility model design can be in order to make the winding of high voltage large capcity transformer, satisfy transformer by direct current to interchange or from the specific (special) requirements of AC-to DC conversion.
