Abstract :
The influence of the geometrical configuration of three single-core cable lines on the generated magnetic field is evaluated in the preliminary analysis. Numerical and experimental procedures are applied to estimate the performances of open or closed shields made of conductive or magnetic materials. A new high-voltage single-core "green cable" is proposed, in which the aluminum conductor is coiled by a double-layer shield realized with copper wires and a ferromagnetic sheath.
