Heat dissipation characteristics and ampacity analysis of three-phase underground cables with detailed soil thermal conductivity modeling

To satisfy the growing demand of power transmission in urban regions especially from the renewables such as
solar and wind, the three-phase underground cable lines have become one of the most attractive solutions
which fit both the space and landscaping requirements. The heat generation and energy dissipation
characteristics of these underground cable assemblies directly determine the cable ampacity and operation
performance. This project will create and validate a thermal model for three-phase cable assemblies in a
metallic ventilated enclosure; both in free air and within a concrete box. This study will benefit the partner
organization by allowing the design engineers to model variable types of cable assemblies that are not covered
in standards or electrical codes.
