The invention relates to a high temperature high bonding strength transposed lead and a manufacturing process thereof, particularly relates to an electromagnetic wire with hardness above 200MPa and belongs to the technical field of a transformer winding wire. According to the process, two sets of leads are arranged, and an intermediate lining paper (5) is arranged between the two sets of leads to separate the two sets of leads; all the enamelled wires form a lead bundle, and the lead bundle is externally provided with an over-cladding layer (4); and the over-cladding layer is an insulation net band bond and wound outside the lead bundle. The process is advantaged in that stress RP0.2 reaches 240-260Mpa when plastic elongation is 0.2%, resistivity is still smaller than 0.01717omegamm<2>/m, elongation is greater than 18%, the intermediate lining paper is used for preventing conductors from bumping in a transformer coil winding process of the transposed lead, and insulation influence is further avoided; the winding wire is bond through the net band or ropes, so a contact area of the lead and transformer oil is improved, circulation of the transformer oil is facilitated, heat radiation performance of the conductor can be improved, and cost reduction is realized.
