Underground cables are intensively used, especially for transporting energy in urban areas. In general, the currents flowing in the cables change, following the loads profile. Moreover, the optimal installation of these cables must consider geometry, magnetic fields and arrangement costs. This paper proposes and analyses different statistical calculations of these optimal locations. The application of the methods to real data demonstrates the effectiveness of the statistical approaches in terms of costs and magnetic fields.
