The uninsulated coil is formed by directly winding superconducting tapes, no insulation exists between the tapes, and current can flow randomly between turns, so that the uninsulated coil has high thermal stability and robustness and has wide application prospects in devices such as controllable nuclear fusion, particle accelerators and the like. The resistance between turns (i.e. turn-to-turn resistance) is an important parameter of the uninsulated coil, the turn-to-turn resistance not only includes the characteristic resistances of the substrate layer, the buffer layer, the silver stabilization layer and the metal encapsulation layer in the superconducting tape, but also includes the interface resistance of the contact surface between the tape and the tape, and the parameter not only affects the excitation time and the excitation loss of the uninsulated coil, but also has an important effect on the magnetic field distribution of the uninsulated coil. The turn-to-turn resistance test method comprises two methods, one is to obtain macroscopic coil turn-to-turn resistance through the charging and discharging time of an uninsulated coil, the other is to obtain the turn-to-turn resistance distribution of each turn of the coil through local magnetic field scanning, through the research of domestic and foreign experts, the uninsulated turn-to-turn resistance is related to the tension of the coil when the uninsulated turn-to-turn resistance is wound, and the turn-to-turn resistance tends to increase along with the increase of the radius because the tension is not uniformly distributed along the radius direction and the tension on the inner side is larger than that on the outer side.

In the straight section, since the hoop pressure (hop stress) cannot be applied from the outside to the inside like the arc coil, the inter-turn resistance tends to be abnormally distributed.
Therefore, in order to ensure that the turn-to-turn resistance of the special-shaped coil is uniformly distributed in each turn, a special auxiliary workpiece needs to be manufactured to apply lateral positive pressure to the straight line segment and control the turn-to-turn tension to be uniform so as to achieve the effect of uniform turn-to-turn resistance.
