The toroidal field (TF) magnet in Tokamak system is required generate a high-steady field to confine and shape the high-temperature plasma. To secure high current density and high thermal stability, the no-insulation(NI) winding technique is used in the fabrication of TF magnet. During plasma operation, heat generated in the TF magnet due to the interaction with central solenoid(CS) coils, poloidal field(PF) coils and the plasma current. The heat generated in NI coils is complex due to the existence of current flow between adjacent turns, thus, it is necessary to calculate the thermal problems. This paper presents the thermal behavior of a NI toroidal magnet under different operating conditions, considering the effect of turn-to-turn contact resistance. The analysis procedure combine FEM and equivalent circuit model. This analysis has applicability and practical directive to the design of cryogenic cooling system for NI toroidal magnet.
