Electrical cables and optical waveguides are disclosed as including an electrically insulative foam. The electrically insulative foam can coat at least one electrical conductor of the electrical cable. The electrically insulative foam can coat the optical fiber of the waveguide. The electrically insulative foam can also define a waveguide.

The present disclosure relates to a cable assembly including a sleeve and a plurality of cables that extend through the sleeve. The cable assembly also includes a grommet positioned within the sleeve at a location offset from one end of the sleeve. The grommet forms a dam location. The cable assembly further includes a bonding material at least partially filling a region of the sleeve located between the dam location and the end of the sleeve. The bonding material bonds the fiber optic cables and the grommet relative to the sleeve. The cables extend through the grommet and the bonding material and include break-out portions that extend outwardly beyond the end of the sleeve.

The present disclosure relates to a flexible cable for use in moving applications, comprising: one or more insulated cores; a filler layer surrounding the one or more insulated cores, having an external surface defining a filler layer external perimeter substantially forming a closed convex polygonal chain with a plurality of line segments connecting consecutive vertices; and an outer sheath surrounding the filler layer and directly applied on the filler layer, having an external surface defining an outer sheath external perimeter forming a continuous closed curve.

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 mobile dedicated cable for a medical Computed Tomography (CT) bed, having an inner sheath layer, a first Teflon® belt, a signal cable layer, a second Teflon® belt, a braided layer and an outer sheath layer, which are coaxially arranged from inside to outside in sequence. The inner sheath layer has a PVC filling strip wrapped by the first Teflon® belt, and a plurality of bulletproof filaments arranged in the center of the PVC filling strip. The signal cable layer has a plurality of signal lines evenly arranged therein, each of which are circumscribed with the first Teflon® belt and the second Teflon® belt, and with two signal lines adjacent thereto.

A deep sea lifting cable having a cable core (36) surrounded by armouring (32), wherein the armouring is surrounded by an outer jacket (33), wherein the cable core comprises at least one power cable (10) is disclosed. The armouring (32) comprises synthetic stiff ropes and interstices (35) between the stiff ropes are filed with a high viscous filler.

The present disclosure relates to a flexible cable for use in moving applications, comprising: one or more insulated cores; a filler layer surrounding the one or more insulated cores, having an external surface defining a filler layer external perimeter substantially forming a closed convex polygonal chain with a plurality of line segments connecting consecutive vertices; and an outer sheath surrounding the filler layer and directly applied on the filler layer, having an external surface defining an outer sheath external perimeter forming a continuous closed curve.

A power cable including: a conductor, an insulation system including an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer arranged around the insulation layer, an elastic mechanical support layer arranged around the outer semiconducting layer, a metallic water blocking layer having a longitudinal weld seam, the metallic water blocking layer being arranged around the mechanical support layer, wherein the mechanical support layer is permanently thermally expanded radially as a result of a heat treatment process, thereby mechanically supporting the metallic water blocking layer.

A cable includes a cable core including a linear filler, and a plurality of core wires for signal transmission, a shield layer covering around the cable core, and a sheath covering around the shield layer. The filler includes a first filler provided at a cable center, and a plurality of second fillers provided around the first filler to form a cross-shape with the first filler in a cross-section perpendicular to a cable longitudinal direction. The cable core is configured in such a manner that the plurality of core wires and the plurality of second fillers are spirally twisted around the first filler to be alternately arranged in a circumferential direction.

The present disclosure relates to a cable assembly including a sleeve and a plurality of cables that extend through the sleeve. The cable assembly also includes a grommet positioned within the sleeve at a location offset from one end of the sleeve. The grommet forms a dam location. The cable assembly further includes a bonding material at least partially filling a region of the sleeve located between the dam location and the end of the sleeve. The bonding material bonds the fiber optic cables and the grommet relative to the sleeve. The cables extend through the grommet and the bonding material and include break-out portions that extend outwardly beyond the end of the sleeve.
