Abstract
Official abstract text for this publication.
A noise suppression cable includes a conductor wire, and a magnetic insulation layer on a periphery of the conductor wire. The magnetic insulation layer includes an insulating material and two or more types of magnetic powders that have different frequency characteristics from each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A noise suppression cable, comprising: a conductor wire; a magnetic insulation layer on a periphery of the conductor wire, wherein the magnetic insulation layer comprises an insulating material and two or more types of magnetic powders that have different frequency characteristics from each other; and a second magnetic insulation layer on a periphery of the magnetic insulation layer, wherein the second magnetic insulation layer comprises at least one type of magnetic powder that has a different frequency characteristic from the two or more types of magnetic powders. 2. The noise suppression cable according to claim 1 , wherein at least one of the two or more types of magnetic powders comprises a flat-shaped magnetic powder, and wherein a flat direction or in-plane direction of the flat-shaped magnetic powder is oriented along a longitudinal direction and a circumferential direction of the cable. 3. The noise suppression cable according to claim 2 , wherein a flattening ratio represented by maximum length/thickness of the flat-shaped magnetic powder is not less than 2 and not more than 50. 4. The noise suppression cable according to claim 1 , wherein a mixture ratio of the two or more types of magnetic powders to the insulating material in the magnetic insulation layer is 5 to 60 vol %.
