The computer modeling of the magnetic field distribution for underground extra-high voltage cable line (330 kV) with ferromagnetic shield of various shapes is performed. As shown, the use of H-shaped shield without any gaps gives a possibility to provide the safe level of magnetic field on the ground above the cables. The dependence of magnetic field level on the thickness of H-shaped ferromagnetic shield is analyzed. References 11, figures 3
Key words: underground cables, extra-high voltage power cable line, ferromagnetic shield, electromagnetic safety, computer modeling.
