This application note studies the thermal performance of a crosslinked polyethylene (XLPE)–insulated power cable subjected to load currents from 300 A to 1600 A. A simplified 3D model includes the copper conductor, XLPE insulation, polyethylene layer, and external PVC sheath, with Joule losses in the conductor used as heat sources for the thermal calculation. The analysis predicts magnetic flux density, temperature distribution, and maximum operating temperature as a function of current, showing peak temperature at the conductor surface and a radial decay toward the outer jacket. Computed temperatures agree closely with published 2D reference results, confirming the suitability of finite element modelling for rating XLPE cables and checking thermal margins under service conditions.
