Abstract
Provided herein is a multi-core cable through which positions of a plurality of insulated conductors and a plurality of non-insulated conductors in a cross section in a longitudinal direction are changed and a likelihood of transmission performance being reduced is low. A multi-core cable includes n conductor bundles.
Claims8
A multi-conductor cable comprising:
- n conductor bundles,
- wherein the n conductor bundles each include at least one insulated conductor and at least one non-insulated conductor,
- a frequency of appearance of the same surface in cross sections perpendicular to a longitudinal direction is AF(N) (N=1 to n) per unit length,
- at least one AF(N) (N=1 to n) is different from the others,
- the ratio between the number of insulated conductors and the number of non-insulated conductors in each of the n conductor bundles is in a range of 2:3 to 4:1,
- a non-insulated conductor paired with an insulated conductor is not fixed, and
- each of the insulated conductors is paired with a non-insulated conductor of the same conductor bundle and/or a non-insulated conductor in a different conductor bundle.
