A quad-shield coaxial cable includes an insulator portion configured to encircle an inner conductor portion, an inner conductive foil portion configured to encircle the insulator portion, an inner braided shield portion configured to encircle the inner conductive foil layer portion, an outer braided shield portion configured to encircle the inner braided shield portion, an outer conductive foil portion configured to encircle the outer braided shield portion, and a jacket portion configured to encircle the outer conductive foil portion.

A cable includes a line for signal transmission or power source supply, a first metal wire having flexibility and a shape-retaining property, a plurality of yarns extending substantially in the same direction as that of the first metal wire, and a coating material for coating the line, the first metal wire, and the plurality of yarns.

One cable shielding has a first metal shielding braided along a length of a cable, a CNT paper shielding surrounding the first metal shielding along the length of the cable, and a second metal shielding braided about the CNT paper shielding along the length of the cable.

A communication cable contains: at least one signal line including a pair of insulated wires placed side by side, each insulated wire having a conductor and an insulation covering which covers the conductor; a shielding body which covers the at least one signal line; a sheath which covers the shielding body; and a bend restricting member which restricts bending of the at least one signal line in a lateral direction a which is a direction along which the pair of insulated wires are placed side by side, as compared with bending of the at least one signal line in a vertical direction intersecting the lateral direction.

A cable hose suitable for welding or cutting systems includes tubing, one or more conductors, and an annular electromagnetic interference (EMI) shield. The EMI shield is disposed radially interiorly of at least a portion of the tubing and radially exteriorly of the one or more conductors. Thus, the EMI shield: (1) prevents EMI emanating from the one or more conductors from exiting the cable hose radially; and (2) conducts current between components of a welding or cutting system.

An improved electrical cable design for high-speed, low loss signal transmission. The improved cable design may be a three-conductor cable having a center conductor, a middle conductor and an outer conductor, where each conductor is separated by a dielectric layer. The electrical cable provides an inverted cable design, in which signal transmission occurs within the middle conductor, the center conductor is used as a return or drain line to ground and the outer conductor is used as a shield. The middle conductor of the electrical cable provides a larger surface area for signal conductance than the center conductor, thereby transmitting signals with significantly less loss (e.g., at least 50% less loss).

An article of manufacture comprising a first section having a first dielectric material and a second section having a second dielectric material and provided on an outer surface of the first section. The second dielectric material of the second section is more flexible than the first dielectric material of the first section, and the second section comprises elements of an organic material located partially on an outer surface of the second section. A coaxial cable using the article of manufacture and a method of manufacturing of the article are also disclosed.

Carbon nanotube cabling is presented herein. One cable comprises a first conductive core comprising a strand of carbon nanotubes electroplated with silver and copper, a first insulator surrounding the first core along a length of the cable, a second conductive core comprising another strand of carbon nanotubes electroplated with silver and copper, a second insulator surrounding the second core along the length of the cable, a shielding surrounding the two insulators along the length of the cable, and an outer jacket configured along the length of the cable. The shielding may be configured from electroplated carbon nanotubes that have been braided, electroplated carbon nanotube paper, or a combination thereof.

The present invention relates to a coaxial cable, and particularly to a small-diameter coaxial cable for use in frequency bands of 100 MHz or more. The present invention addresses the problem of providing a coaxial cable which has excellent flexibility, a small outer diameter, and excellent shielding characteristics. The problem is solved by a coaxial cable having an outer conductor which is formed by mixing and laterally winding strands in the same direction, the strands having an outer diameter difference of not less than 10% between a large-diameter strand having a maximum outer diameter and a small-diameter strand having a minimum outer diameter.

Systems and methods for tamper proof cables are described herein. In certain implementations, a system includes one or more pieces of equipment and one or more tamper proof cables connecting the equipment within a network. A tamper proof cable includes a core that provides a transmission medium through the cable; an insulator enveloping the core; a first conductive braid encircling the insulator; a dielectric enveloping the first conductive braid; and a second conductive braid encircling the dielectric, the first and second conductive braids, and the dielectric forming a capacitor. The system includes one or more detectors, each detector coupled to the tamper proof cables, each detector and an associated capacitor forming a tuned circuit, the detectors providing a signal when an associated portion of the tamper proof cables is tampered with; a monitor coupled to the detectors that notifies an infrastructure management system when the signal is received.
