Abstract

In order to improve the quality of low voltage UV cross-linking product and provide a theoretical basis to the improvement of cross-linking device, the temperature field of cross-section of cable was studied based on the theories of semi-transparent medium radiation and numerical heat transfer in this article. Two cases with different convective heat transfer coefficient of cable surface were researched, and then the temperature distribution in the cable under different boundary conditions of heat convection was analyzed. At last, the temperature field characters of insulating layer and conductor cores in the cable were achieved and a reasonable value range of convective heat transfer coefficient of cable surface was given in this article.
