Abstract :
A finite element (FE) iterative formulation has been used for the computation of the coupled magneto-thermal field in underground SF6 insulated high voltage cables. The formulation takes into account the real geometrical and physical properties of the involved materials. Using the field distributions, the cable ampacity and losses, the forces and the inductances have been calculated for both isolated phase and three-conductor arrangements. The influence of the operating parameters on these quantities is examined
