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.

In an electronic cable, a shielding tape prevents and mitigates the creation and propagation of micro-fractures and the deleterious effects thereof. In some embodiments, the shielding tape has layers which are oriented in a non-zero transverse relation with respect to each other, or have been treated to have non-zero orientations. Other embodiments include micro-fracture propagation mitigation means, such as perforations, ridges, waffling, and dimpling. In some embodiments, the layers of the shielding tape are bonded to each other with an electrically-conductive elastomeric adhesive. In other embodiments, the shielding tape is wrapped around a cable's dielectric and form an overlap gap, which is filled by an electrically-conductive elastomeric adhesive.

Cables that include a conductor and an optical fiber. In some embodiments, the cable can include an optical fiber loosely disposed within an enclosure. A conductor layer can be disposed about the enclosure. An insulation layer can be disposed about the at least one conductor layer. An inner layer of armor strength members can be helically disposed about the insulation layer. An outer layer of armor strength members can be helically disposed about the inner layer of armor strength members. The armor strength members in the outer layer of armor strength members can be at an opposite helix compared to the armor strength members in the inner layer of armor strength members. An outer jacket can be disposed about the outer layer. In other embodiments, the cable can include an optical fiber in a coupled electro-optical package, where the conductor layer can be disposed about the electro-optical package.

Power umbilical (1) comprising a plurality of power cables (7) for electric power transmission, elongated filler elements (5), and an outer sheath (3). The elongated filler elements (5) abut against each other at abutment faces (5a), thereby forming a complete ring enclosing the power cables (7). The elongated filler elements (5) comprise cable recesses (5b) within which the power cables (7) are embedded. The power umbilical (1) further comprises one or more friction control profiles (13, 15, 116), wherein the material of the friction control profile (13, 15, 116) is softer than the material of the elongated filler elements (5). The one or more friction control profiles (13, 15) are arranged in a deformed state.

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.

In an electronic cable embodiment, a shielding tape includes a first metallic layer having a first orientation along which micro-fractures are predisposed to form, and a second metallic layer having a second orientation along which micro-fractures are predisposed to form. The first and second orientations have a non-zero transverse relation with respect to each other. An adhesive is disposed between the first and second metallic layers. Metallic solids are dispersed throughout the adhesive so as to define the adhesive with electrically conductive material characteristics.

A fluororesin cable can include an electric wire having a central conductor covered with an insulator, an inclusion, a tape made of a resin, and a sheath made of a fluororesin. The inclusion is arranged along the electric wire. The tape is wound around an outer periphery of an aggregate of the electric wire and the inclusion. The sheath entirely covers the aggregate and the tape. Here, a material for the inclusion is harder than a fluororesin material constituting the sheath.

Audio cables including a conductor spirally wrapped in a non-conductive thread to centrally position the conductor within a channel comprising mostly air include a first conductor having a first diameter, and a non-conductive thread spirally wrapped around the center conductor, the non-conductive thread having a second diameter. A first jacket surrounds the center conductor and thread, having an inner diameter approximately equal to the first diameter plus twice the second diameter. A second conductor surrounds the first jacket and/or the center conductor and thread. In many implementations, the first diameter is less than the second diameter. A radially symmetric filler comprising a plurality of arms may form a corresponding plurality of channels.

A power cable and filler device adapted to bear against a first and second power cores in a power cable, including a first arced wall which defines a portion of a first circle having a first diameter, a second and third arced wall, each defining a portion of a second circle having a second diameter which is smaller than the first diameter. A chamber is formed between the first, second and third arced walls.

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.
