Title:
METHOD FOR SHIELDING THE MAGNETIC FIELD GENERATED BY AN ELECTRICAL POWER TRANSMISSION LINE, AND MAGNETICALLY SHIELDED ELECTRICAL POWER TRANSMISSION LINE
Document Type and Number:
WIPO Patent Application WO2003003382
Kind Code:
A8
Abstract:
The present invention relates to a method for shielding, the magnetic field generated by an electrical power transmission line comprising at least one electrical cable. This method comprises the provision of a magnetic shield in a position radially external to said at least one electrical cable, said magnetic shield comprising at least one pair of shielding layers made from different ferromagnetic materials, radially superimposed and having their maximum relative magnetic permeability increasing in a radial direction from the inside towards the outside of said magnetic shield. The present invention also relates to an electrical power transmission line provided with multiple-layer magnetic shield, and a multiple-layer magnetic shield.
