Abstract

This research leverages 2D COMSOL Multiphysics software to simulate the performance of various underground cable laying configurations, specifically tailored to Malaysia's harsh climate marked by high humidity and diverse soil compositions. By focusing on temperature distribution and the thermal conductivity of insulation materials such as XLPE and HDPE, the study emphasizes the crucial role of soil thermal conductivity in heat dissipation. Findings indicate that higher soil thermal conductivity significantly reduces thermal stress, leading to lower operational temperatures and extending cable lifespan. The optimal configurations, combined with appropriate insulation materials, mitigate thermal hotspots and ensure even temperature distribution. This research provides comprehensive guidelines for designing and installing resilient and sustainable underground cable systems, enhancing the reliability and cost-efficiency of power distribution networks in Malaysia's unique environmental conditions.
