Energy efficient noise dampening cables
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.
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.
