A shielded wire includes an electrical wire including a conductor portion and a covering portion, a shield braid in which electrically conductive wire members are braided, and which covers an outer circumference of the electrical wire, a tubular sheath disposed on an outer circumference of the shield braid and made of an insulating resin.

A coaxial cable and method of construction thereof are provided. The coaxial cable includes an elongate central conductive member; a dielectric insulative layer encasing the central conductive member; an outer protective sheath, and a braided EMI shield layer including hybrid yarn sandwiched between the dielectric insulative layer and the outer protective sheath. The hybrid yarn includes an elongate nonconductive filament and an elongate continuous conductive wire filament. The wire filament is interlaced in electrical communication with itself or other wire filaments along a length of the EMI shield layer to provide protection to the central conductive member against at least one of EMI, RFI or ESD. The method includes providing a central conductive member; forming a dielectric insulative layer surrounding the central conductive member; braiding an EMI shield layer including hybrid yarn about the insulative layer, and forming an outer protective sheath about the braided EMI shield layer.

The invention relates to an electrical cable (100) for exchanging communication signals between two devices, particularly a cable (100) that can be integrated into a catheter or a guidewire (5). The cable (100) comprises at least one pair (120, 130) of differential wires (D1+, D1, D2+, D2) that are, during operation, supplied with opposite voltages, thus defining a voltage-neutral plane (VNP) between them. Moreover, the cable (100) comprises at least one set (140) of single-ended wires (S11, S12; S21, S22; S31, S32) that is arranged symmetrically with respect to said voltage-neutral plane (VNP). Optionally a core wire (110) may be used for providing mechanical stability and additional electrical functionality. Electromagnetic disturbances from the differential wires to the single-ended wires (and vice versa) are minimized due to the particular arrangement of wires.

An electrical cable includes at least one conductor assembly. Each conductor assembly includes at least one inner conductor that extends along a length, an insulator, and a shield layer. The insulator engages and surrounds a surface of the at least one inner conductor. The insulator is composed of a dielectric material. The shield layer engages and surrounds an outer perimeter of the insulator. The shield layer is formed of a conductive plastic material to provide electrical shielding for the at least one inner conductor and flexibility.

High bandwidth push-cables for high speed image or video data transmission between a camera head and a cable reel or camera control unit (CCU) are disclosed.

A coaxial cable includes: an inner conductor; a dielectric layer surrounding the inner conductor; an outer conductor surrounding the dielectric layer and having a plurality of corrugations, wherein each of the corrugations has a root and a crest connected by a transition section; a jacket surrounding the outer conductor; and a first adhesive layer interposed between the dielectric layer and the roots of the corrugations of the outer conductor. Each of the roots has a curved flattened portion that is adhered to the first adhesive layer.

A coaxial cable includes: an inner conductor; a dielectric layer surrounding the inner conductor; and an outer conductor having a plurality of corrugations. Each of the corrugations has a root and a crest connected by a transition section. The root has a first radius of curvature, the crest has a second radius of curvature, and the ratio of the first radius of curvature to the second radius of curvature is equal to or greater than 1.

A communication cable 1 is provided with a conductor 2, an insulation layer 3 containing an organic polymer and covering an outer periphery of the conductor 2, a metal foil 5 for covering an outer periphery of the insulation layer 3, and a magnetic sheath layer 7 containing an organic polymer and a powdered magnetic material and covering an outer periphery of the metal foil 5. A tensile modulus of elasticity of the magnetic sheath layer 7 is lower than that of the insulation layer 3. Assuming that an organic polymer having a melting point of 100 C. or lower is a low melting point polymer and a mass ratio of the low melting point polymer to organic polymer components constituting each layer is a low melting point component ratio, the low melting point component ratio is larger in the magnetic sheath layer 7 than in the insulation layer 3.
