The effects of sand and pipes on the temperature distributions of the underground cable

Abstract

With the proliferation of underground systems and technologies, the investigation of thermal fields in the soil has become a subject of great attention in the emerging technology of buried structures. In this work, the heat transfer mechanisms in underground cable installations have presented. This paper considers a system of the underground cable of 12/20 (24) kV single core cable with a copper conductor and XLPE insulation, located in three models were designated for the experiment, a cable was located in (sand, PVC pipe, and an aluminum pipe). Furthermore, its reviews the results were obtained from a laboratory model where a wooden box was used, and the cable was placed inside the box by burying the cable in three different designs and using the soil used in Iraq and obtained a good results and comparisons were made at each model.
