Abstract
The results of numerical simulation of temperature modes of cross-linked polyethylene (XLPE) cable under transient states for International Thermonuclear Experimental Reactor (ITER) application are presented. The pulsed electric current load in the external circuit rapidly changes with the maximum values of 1.5 kA during tens of seconds decay with a period of 1200 s that corresponds to operation modes of the ITER fusion reactor. The core temperature achieves periodic steady-state at 20000 s, which is consistent with 4-5 cable thermal constant (~ 4500 s). The numerical results obtained reveal that the skin effect plays an insignificant role on core temperature dynamics. Multiphysics model links electric current with heat generation in cables with respect to electromagnetic effects and measured temperature dependencies of electro and thermophysical properties of the cable’s XLPE insulation.
