An electric cable has at least one elongated electrical conductor (1), at least one electrically insulating layer (2) surrounding the elongated electrical conductor (1), and at least one metal layer (3) surrounding electrically insulating layer (2). The metal layer (3) has metal nanowires.

A composite cable includes a signal transmission cable including a pair of signal lines being arranged parallel to each other in a cable longitudinal direction and contacting to each other and a shield layer covering the pair of signal lines together, a pair of power supply lines being arranged contacting to each other and contacting to the shield layer, a collective braided shield covering around a cable core composed of the signal transmission cable and the pair of power supply lines collectively, a sheath covering around the collective braided shield. The collective braided shield is configured closely contacting to the shield layer in accordance with an outer shape of the shield layer.

A guarded coaxial cable assembly including at least a pair of conductors, one or more rails, and a jacket covering these parts such as a first rail extending alongside two nearby conductors, the rail and the conductors embedded in an outer electrically insulating jacket, the outer jacket having a pair of generally opposed bearing surfaces for bearing transverse loads, the rail operative to reduce outer jacket deformations resulting from transverse loads applied to the bearing surfaces; and, the orientation of the rail and the conductors within the outer jacket operative to limit conductor or conductor jacket deformations resulting from transverse loads applied to the bearing surfaces.

A composite cable includes a wire bundle and an outer layer sheath that covers the wire bundle. The wire bundle includes single-core first and second electric wires, a double-core twisted pair electric wire, and first, second, and third wire-shaped fillers. In a cross-sectional view, the wire bundle includes a wire unit in which the first and second wires and the twisted pair wire are arranged in contact with one another. In an imaginary circumscribed circle circumscribing the wire unit, the first wire-shaped filler is disposed in a first space between the first wire, the second wire, and the imaginary circumscribed circle, the second wire-shaped filler is disposed in a second space between the second wire, the twisted pair wire, and the imaginary circumscribed circle, and the third wire-shaped filler is disposed in a third space between the twisted pair wire, the first wire, and the imaginary circumscribed circle.

A submarine power cable having: a power core including a conductor, wherein the conductor has a conductor joint in a joint region of the power core, a main armor layer including a plurality of main armor wires arranged around the power core and extending in the axial direction of the power core, and a joint reinforcement armor layer including a plurality of joint reinforcement armor wires axially locked relative to the main armor wires, wherein the joint reinforcement armor layer is provided only in the joint region and arranged layered with the main armor layer, the joint reinforcement armor layer and the main armor layer thereby forming a dual-layer armor only in the joint region.

Disclosed is an armored cable assembly including a core having a notched assembly tape about a plurality of conductors. A metal sheath surrounds the core.
