Abstract

Energy efficient noise dampening coaxial and twisted pair cables include certain layers to improve the quality of signals transmitted over the cables. A coaxial cable includes a conductive core, a first insulating layer surrounding the conductive core, a metal shield layer surrounding the first insulating layer, a second insulating layer surrounding the metal shield layer, a carbon material layer surrounding the second insulating layer, and a protective sheath wrapping the carbon material layer. A twisted pair cable section includes a core section. The core section includes a carbon material core, an insulating layer surrounding the carbon material core, and a metal shield layer surrounding the insulating layer. A plurality of twisted pair cables are disposed in sections or compartments defined by the core section, and between the core section and a protective sheath. Methods for constructing the cables are also disclosed.

Claims

1. A cable, comprising:

an electromagnetic dampening core section, the core section including;

a carbon material core formed of strands of carbon fiber;

a substantially solid and contiguous metal shield layer; and

an insulating layer disposed between the carbon material core and the metal shield layer;

a protective sheath wrapping the core section; and

a plurality of twisted pair cables disposed between the core section and the protective sheath,

wherein a cross section of the core section and the carbon material core is in a shape of a cross with substantially rectangular protrusions forming at least four different sections with each of the twisted pair cables disposed in a corresponding one of the at least four sections.

2. The cable of claim 1, wherein each of the twisted pair cables includes a first cable member and a second cable member.

3. The cable of claim 2, wherein each of the first and second cable members includes an insulating layer surrounding a conductive core.

4. The cable of claim 1, wherein the electromagnetic dampening core section forms an electromagnetic dampening zone between the twisted pair cables, thereby reducing electromagnetic interference between the twisted pair cables.

5. The cable of claim 1, wherein the thickness of the substantially solid and contiguous metal layer is up to 1 millimeters in thickness.
