A long electric cable generates heat at a rate qc. Half the cable is buried underground while the other half exchanges heat by radiation and convection. The ambient and surroundings temperatures are and respectively. The heat transfer coefficient is h.

Neglecting the thickness of the electrical insulation layer and heat loss to the ground, select a model to analyze the temperature distribution in the cable and write the heat equation and boundary conditions.
