The impulse surface flashover voltages of polytetrafluoroethylene(PTFE) in liquid nitrogen were measured. The initial flashover voltages were measured using ring-ring electrodes under different electrode distances, and the experimental results were analyzed by Weibull distribution. The relationship between the impulse surface flashover voltage of 0.1% flashover probability and creepage distance was obtained, which can provide reference to the insulation design of superconducting electric power equipment.
