In this paper, the key role of 60 kV θ-pinch coil insulation of field-reversed plasma device in equipment operation was introduced briefly. Combined with operating conditions, the selecting processes of key parameters and manufacturing process of θ-pinch coil insulation were expounded, and its mechanical properties and insulating properties were tested and analyzed. On the basis of the sample analysis, the corresponding prototype was made to test and analyze. The results show that the field strength of the coil corner can decrease by 41% through optimizing the main insulation thickness reasonably and increasing the insulation fillet properly, making the service life of coil prolong by 9 times, and the breakdown voltage is 20% higher than the design voltage. Compared the ANSYS calculating results with the sample test results, it is found that selecting 8 MPa pressure during impregnation curing can effectively enhance the adhesion. The research results provide ideas for the insulation structure design of 60 kV θ-pinch coil of field-reversed plasma device.
