Thermal Analysis by Conduction Convection and Radiation in a Power Cable

Abstract

In this present paper different models are implemented to study the thermal effects at various installation conditions. When a cable is installed in air, solar and wind effects are taken into consideration to know the effect on cables. The heat generated in the cable that is buried in trenches dissipates heat through the backfill material surrounding the cable. The heat generation decreases with the increase in thermal conductivity of the moist soil. The effect of steam pipe crossing over a cable underground causes the moisture migration from the soil. The results are obtained in COMSOL MULTIPHYSICS software which solves the equations based on finite element method.
