Low noise cable core and manufacturing method thereof and low noise cable using the same

A manufacturing method of a low noise cable core, comprising:

• forming an insulated conductor comprising a conductive core and an insulation layer encapsulating the conductive core;
• forming a first type conductive layer encapsulating the insulated conductor by way of a first forming method;
• and
• forming a second type conductive layer encapsulating the first type conductive layer by way of a second forming method different from the first forming method.

A low noise cable, comprising:

• at least three strands of cable cores, wherein two or more of the adjacent cable cores are in contact with one another, and each of the cable cores comprises:
• an insulated conductor comprising a conductive core and an insulation layer encapsulating the conductive core;
• a first type conductive layer encapsulating the insulated conductor;
• and
• a second type conductive layer encapsulating the first type conductive layer;
• wherein the first type conductive layer and the second type conductive layer are respectively formed by way of a first forming method and a second forming method different from the first forming method;
• and
• an outer sheath encapsulating said at least three strands of cable cores.
