Crosslinked polyethylene (XLPE) cables have good voltage resistance, excellent high-temperature resistance, and good mechanical strength, and are widely used in power systems. This article takes 10 kV XLPE cable as the research object and conducts finite element simulation under temperature electric field coupling. A 2D model of XLPE cable was established using COMSOL Multiphysics finite element software, and relevant electric and temperature field simulation calculations were carried out. The electric field and temperature in XLPE cables were simulated, and the distribution characteristics of electric field and temperature were obtained through finite element calculation when multiple physical fields were coupled inside XLPE cables. The differences in distribution characteristics were simulated when only electric field, temperature, and electric field coupling existed. The research results will provide some reference for the safe operation of XLPE cables.
