Abstract
A communication cable includes a coating layer that contains a powdery magnetic material and that can suppress the occurrence of a powdery substance containing the magnetic material when processing the coating layer. The communication cable further includes a conductor, an insulating coating that covers an outer circumstance of the conductor, and a magnetic sheath layer that covers an outer side of the insulating coating, and the magnetic sheath layer contains the magnetic material and the magnetic material has a particle shape with an average particle diameter of not more than 50 μm and an aspect ratio of not greater than 4.
Claims11
A communication cable comprising:
- a conductor;
- an insulating coating that covers an outer circumference of the conductor;
- and
- a magnetic sheath layer that covers an outer side of the insulating coating,
- wherein the magnetic sheath layer contains a magnetic material, and
- the magnetic material has a particle shape with an average particle diameter of not more than 50 μm, and has an aspect ratio of at least 1.5 and not greater than 4, the average particle diameter representing a D50 value of an equivalent circle diameter in electron microscope observation, and
- the magnetic sheath layer does not contain a magnetic additive with an aspect ratio that is larger than 4, except for unavoidable impurities.
