The technical problem may be solved by an insulating cable comprising a conductor and an insulator configured by a plurality of resin layers on the conductor, wherein the plurality of resin layers contain the same kind of fluorine resin, a difference in refractive index between a resin layer having the largest refractive index and a resin layer having the smallest refractive index among the plurality of resin layers is 0.03 or less, a layer thickness of an outermost resin layer of the insulator is 0.03 mm or less, and a deviation (coefficient of variation CV) in thickness of the insulator in a cross-section perpendicular to a longitudinal direction of the cable is 0.035 or less.

A multicore cable includes a twisted wire portion including a plurality of Twinax cables and a plurality of coaxial cables, and a shield layer disposed on an outer periphery of the twisted wire portion. The twisted wire portion includes a first twisted wire layer and a second twisted wire layer in a cross section perpendicular to a longitudinal direction of the multicore cable. The first twisted wire layer is closest to the shield layer, and the second twisted wire layer is located on a center side from the first twisted wire layer and is adjacent to the first twisted wire layer. A closest Twinax cable is disposed in the second twisted wire layer. The closest Twinax cable is closest to the shield layer among the plurality of Twinax cables included in the twisted wire portion.

A shielded electrical cable includes at least two spaced-apart conductors extending side-by-side along a longitudinal cable direction. An insulation electrically insulates the conductors from each other. A cable shield, together with the conductors, extends along the longitudinal cable direction and annularly surrounds the conductors, as seen in cross section. An electrical device is disposed between the conductors and the cable shield. The electrical device is surrounded by the cable shield and disposed on the conductors such that the electrical device is in electrical contact with each of the conductors.

A coaxial cable comprises inner and outer conductors disposed along an elongate axis, a dielectric insulating material disposed between the inner and outer conductors, a compliant jacket disposed over the inner and outer conductors, and a compliant reinforcing outer layer disposed over the compliant inner jacket, the outer layer being physically separate from the inner jacket and comprising off-axis fibers to react loads incurred during one of two operating modes, i.e., an aerial and an in-ground operating mode.

A data communications cable may communicatively coupled two components associated with an information handling system. For example, the data communications cable may include: a differential pair of conductors; a first dielectric material, associated with a first relative permittivity, surrounding the differential pair of conductors; and a second dielectric material, associated with a second relative permittivity, surrounding the first dielectric material. For instance, the first relative permittivity may be greater than the second relative permittivity, and a distance between the differential pair of conductors may vary plus or minus an amount with a length of the data communications cable.

This invention relates to the technical field of cables and, in particular, to an automatic leakage detection wire, which comprises an insulating protective layer, a plurality of core wires, a detection wire and an additional signal wire, and the detection wire is electrically connected with the additional signal wire. The detection wire and the additional signal wire are all connected to an external signal detection device; the core wire includes a conductor group and a first insulating layer covering the outer periphery of the conductor group; the detection wire, the additional signal wire, and a plurality of the cores. The wires are all wrapped in the insulating protective layer. The automatic leakage detection line provided by the invention can carry out an early warning through the detection line and an additional signal line, thereby reducing the accident risk caused by the damage of the automatic leakage detection line.

Embodiments of the invention provide a hollow cable for conveying radiofrequency and/or microwave frequency energy to an electrosurgical instrument that can fit within, e.g. slide relative to, the hollow cable. The hollow cable provides a bipolar electrical connection to the electrosurgical instrument that is maintained when the electrosurgical instrument is rotated relative to the hollow cable. The cable may comprise a hollow coaxial transmission line having a rotatable component mounted at its distal end. The rotatable component comprises a longitudinal passageway continuous with the hollow coaxial transmission line. The rotatable component is rotatable relative to the transmission line and comprises a first and second conductive portions that are respectively electrically connected to first and second terminals on the coaxial transmission line and which are configured to maintain an electrical connection with their respective terminal when rotated relative to the coaxial transmission line.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is σ1, the center-to-center spacing of the insulated conductors of the second conductor set is σ2, and σ1/σ2 is greater than 0.7.
