WebOct 10, 2014 · All the heat generated by an underground power cable must be dissipated through the soil. This is quantified by the soil thermal resistivity (or thermal rho, °C-cm/W), which can vary from 30 to 500°C-cm/W. The ability of the surrounding soil to transfer the heat determines whether an operating cable remains cool or overheats.
