An electromechanical cable that is crush-resistant and torque balanced is provided as well as a method for manufacturing a crush-resistant and torque balance electromechanical cable. The cable can include a core having a conductor surrounded by a first jacket layer, a second jacket layer surrounding the first jacket layer, a first armor layer surrounding second jacket layer, a third jacket layer surrounding the first armor layer, a second armor layer surrounding the third jacket layer, and a fourth jacket layer surrounding the second armor layer. The first armor layer can be constructed as a plurality of wires and compressed partially into the second jacket layer. The second armor layer can be constructed from a plurality of three-wire strands and/or single wires and compressed partially into the third jacket layer. The three-wire strands can symmetric or asymmetric and can be compacted or non-compacted.

A guarded coaxial cable assembly include one or more conductors, one or more rails, and an outer jacket, the orientation of the rail and the conductor(s) within the outer jacket operative to limit conductor or conductor jacket deformations such as deformations due to bends and transverse loads when the cable assembly is squeezed between a sash and a jamb.

A method of manufacturing an improved overhead or underground telephone lead-in cable for transmission services VVDL (voice, video, data and lead-in) that permits the connection of the users to the public telephone system with a high speed digital service link, besides the analog services required. The cable has at least one or a plurality of transmission circuits. One of the transmission circuit is formed by two metal conductor elements cooperating in turn to self-support the cable or a conventional type of impregnated fibers or kevlar tape. The second circuit which is formed by a stranded pair of conductors is impregnated with a swelling powder preventing moisture penetration.

Ground conductors are disclosed. The ground conductors can include a core made primarily of a first material, such as steel. The ground conductor can include a surrounding sheath, which includes at least one layer made primarily of a second material, such as copper. The ground conductor has a ratio between its width and its thickness of no less than 11.1:1.

A shield including: a plurality of insulating filaments that extend in an X direction; and a plurality of conductive filaments that extend in a Y direction intersecting the X direction and are interknitted with the plurality of insulating filaments, wherein the plurality of insulating filaments includes: a first pair of insulating filaments that are adjacent to each other in the Y direction at a first interval, and a second pair of insulating filaments that are adjacent to each other in the Y direction at a second interval that is larger than the first interval.

A flexible anti-theft protection system for an elongated cable is disclosed. The system comprises a plurality of elongate flexible armor elements disposed parallel to a longitudinal axis of the cable and arranged circumferentially around the cable. A plurality of compressible guide-channel bands are spaced along a length of the cable, each band comprising longitudinal guide channels configured to receive and maintain circumferential positioning of the armor elements. The guide-channel bands are configured to compress radially inward to accommodate cables of varying diameters. The invention also encompasses a method of installing the anti-theft protection system comprising positioning the plurality of elongate flexible armor elements circumferentially around the cable, securing the armor elements using compressible guide-channel bands having longitudinal guide channels that maintain circumferential positioning of the armor elements, and compressing each guide-channel band radially inward against the cable using a fastening member.

In some embodiments, a cable can include an electrically conductive inner core. A first insulation layer can be disposed about the inner core. An electrically conductive layer can be disposed about the first insulation layer. A second insulation layer can be disposed about the electrically conductive layer. A first polymer jacket can be disposed about the second insulation layer. The first polymer jacket can include a first layer of armor strength members disposed therein. A second polymer jacket can be disposed about the first polymer jacket. The second polymer jacket can include a second layer of armor strength members disposed therein. An outer polymer jacket can be disposed about the second polymer jacket. At least one of the first polymer jacket, the second polymer jacket, and the outer polymer jacket can be formed from an aliphatic polyketone polymer, an ethylene-propylene copolymer, a polyolefin elastomer, a polypropylene, or a cross-linkable polyethylene.

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.
