Buried Cables Heating

Application ID: 78351

This model evaluates the temperature distribution in 3 buried cables in a situation where the soil surface temperature is known. The temperature profile obtained with a thermal circuit approach for the cables is compared with a FEM approach. The thermal circuit properties are established using standard representation of buried cables under the Kennelly assumption (uniform soil surface temperature). The superposition principle is used to determine the mutual heating of cables in order to improve the equivalent thermal circuit accuracy.

This model example illustrates applications of this type that would nominally be built using the following products:
