Any cable carrying current will generate heat that must be removed from the cable vicinity or the cable can quickly overheat and sustain damage. The amount of heat generated in the cable is determined by the current and varies with the square of the current.  In the case of a cable installed underground there are three mechanisms by which heat is removed from...
