Construction Material Testing - Thermal Resistivity Test for Dune Sand

The soil thermal resistivity is of a great importance for the design of high voltage cables. Underground cables generate heat as a
result of power losses when transmitting current. This heat must be dissipated in a form that will not affect the performance of
the cables. The presence of moisture normally helps to reduce the thermal resistivity and keeps it within the design range.
