PROBLEM TO BE SOLVED: To provide a support structure which does not degrade magnetic characteristics of a magnetic shield device for shielding an AC cable. SOLUTION: A magnetic body 10 is housed in an aluminum case 15. The magnetic body 10 covered with the aluminum case 15 is prepared in a plurality of numbers to enclose a three-phase AC cable 20 in the plane orthogonal to the cable 20, so that the magnetism leaking from the cable 20 is shielded. The aluminum case 15 comprises a gap for enclosing the cable 20, with an insulator 32 arranged in the gap. An insulator case can be used instead of the aluminum case. COPYRIGHT: (C)2007,JPO&INPIT |
