A cable with braided shield includes a conductor, an insulation layer arranged to cover a periphery of the conductor, a braided shield layer arranged to cover a periphery of the insulation layer, and a sheath arranged to cover a periphery of the braided shield layer. The braided shield layer includes an inner braided shield layer, and an outer braided shield layer provided on a periphery of the inner braided shield layer. The inner braided shield layer includes a braided shield braided to cross metal wires. The outer braided shield layer includes a braided shield braided to cross a copper tinsel wire and a metal wire.

An improved electric cable is disclosed herein. The resistance of the electric cable of the present disclosure is surprisingly decreased despite a reduction in the cross-sectional area of the conductor when at least one metal slug is positioned at an end of the cable. Conductor wires, which may or may not be individually insulated, may extend around a metal slug or through an aperture of the slug. In combination with at least one metal slug, the cross-sectional area of individual wires or the amount of wires within a stranded wire cable may be substantially reduced without seeing an expected proportionate increase in electrical resistance, and surprisingly, a decrease in resistance may be observed.

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.

Fire-resistant coaxial cables are described as well as methods to manufacture them. The dielectric between the coax cable's central conductor and outer coaxial conductor ceramify under high heat, such as those specified by common fire test standards (e.g., 1850 F./1010 C. for two hours). The dielectric can be composed of ceramifiable silicone rubber, such as that having a polysiloxane matrix with inorganic flux and refractory particles. Because thick layers of uncured ceramifiable silicone rubber deform under their own weight when curing, multiple thinner layers are coated and serially cured in order to build up the required thickness. A sacrificial sheath mold is used to hold each layer of uncured ceramifiable silicone rubber in place around the central conductor while curing. The outer conductor can be a metal foil, metal braid, and/or corrugated metal. Another layer of extruded ceramifiable silicone dielectric or an outer wrap of ceramic fiber yarn surrounds the outer conductor and continues to insulate it from the outside if a low smoke zero halogen jacket burns away. Methods of testing and installation are described.

A cable with braided shield includes a conductor, an insulation layer arranged to cover a periphery of the conductor, a braided shield layer arranged to cover a periphery of the insulation layer, and a sheath arranged to cover a periphery of the braided shield layer. The braided shield layer includes a braided shield braided to cross a copper tinsel wire and a metal wire. An outer diameter D1 of the copper tinsel wire is larger than an outer diameter D2 of the metal wire.

A wire includes an elongate conductive core wire, an elongate insulating layer disposed on and surrounding the elongate conductive core wire, an elongate conductive shield wire disposed adjacent to the insulating layer and the elongate conductive core wire, an elongate conductive shield layer disposed on the insulating layer and on the conductive shield wire such that the elongate insulating layer, the elongate conductive core wire, and the elongate conductive shield wire are embedded in the elongate conductive shield layer, the elongate conductive shield wire being electrically connected to the elongate conductive shield layer.

Systems and methods presented herein provide reduced weight cabling using carbon nanotubes. In one embodiment, a cable comprises a conductive core comprising a strand of carbon nanotubes electroplated with silver and copper, a shielding surrounding the core along a length of the cable, and a jacket surrounding the shielding along the length of the cable.
