The current carrying capacity of a power cable determines its efficiency, which depends on its capability to dissipate heat produced inside the cable, as a result of current flow, into the surrounding. The studies were conducted to determine how the characteristics of the medium around the cable affected its temperature and, as a result, its ability to transport electricity. The experimentation in the lab and real measurements of the temperature values at various locations in the casing pipe constitute the article's uniqueness. The article presents an innovative concept of a laboratory stand, designed to measure the dissipation of heat emitted by a cable in separated casing pipes with the content of various filling materials. The assessment of heat removal is made based on the recorded distribution of temperatures in individual casing pipes. The experimental setup was suitably compatible with the assumptions used for the research, according to the early findings of comparison investigations. It has been demonstrated for the instance under investigation that using the right fillers around the cable may reduce cable temperature, boost the cable's current carrying capability, and provide more efficient heat dissipation.
