Abstract: Intermittent large alternating current in the thermonuclear fusion time passes through the power cable, causing the cable temperature to rise and damaging the cable insulation. To solve the problem, a transient thermal path model is proposed to study the change of cable temperature by using iterative optimization algorithm, and the structure of the cable is optimized. The correctness of the cable temperature intermittent high pulse current is verified through tests, which provides a basis for the development of thermonuclear fusion cable.

Key words: nuclear fusion, intermittent alternating current, iterative optimization algorithm, temperature change
