Methods for manufacturing shield structures for use in communication cables
Methods for forming continuous shields for use in a cable are provided. A first layer of longitudinally extending dielectric material may be provided, and a second layer of longitudinally extending electrically conductive material may be formed on the first layer. At a plurality of spaced locations along a longitudinal direction, respective gaps may be formed through both the first layer and the second layer, and each gap may span partially across a width of the second layer. Additionally, at each of the plurality of spaced locations, the gaps may result in the formation of one or more fusible elements of the electrically conductive material spanning between an adjacent set of longitudinally spaced segments of the electrically conductive material. Each fusible element may provide electrical continuity between the adjacent set of longitudinally spaced segment and may further have a minimum fusing current between 0.001 amperes and 0.500 amperes.

A cable includes a core having a length, a jacket coaxially surrounding the core along the length, and a non-flowing floodant between the core and the jacket. The non-flowing floodant is disposed circumferentially and in a segmented manner such that the coaxial drop cable is configured to include a plurality of first areas, separated from one another along the length, that include the non-flowing floodant, and second areas, separated from one another along the length by a respective one of the first areas, having a space between the jacket and the core without the non-flowing floodant. The non-flowing floodant is configured to circumferentially seal a space between the core and the jacket at the plurality of first areas. Two consecutive ones of the plurality of first areas are configured to contain moisture in the second area between the two consecutive ones of the plurality of first areas.
Coaxial Cable Utilizing Plated Carbon Nanotube Elements And Method Of Manufacturing Same
A cable includes at least one inner conductor and an insulation layer surrounding the inner conductor. An outer conductive layer surrounds the insulation layer and center conductor and includes a carbon nanotube substrate having opposing face surfaces and edges. One or more metals are applied as layer(s) to the opposing face surfaces and edges of the carbon nanotube substrate for forming a metallized carbon nanotube substrate. The metallized carbon nanotube substrate is wrapped to surround the insulation layer and center conductor for forming the outer conductive layer. Embodiments of the invention include a braid layer positioned over the outer conductive layer. The braid layer is woven from of plurality of carbon nanotube yarn elements made of a plurality of carbon nanotube filaments. The carbon nanotube filaments include a carbon nanotube core and metal applied as a layer on the carbon nanotube core for forming a metallized carbon nanotube filaments and yarns woven to form the braid layer.
Fire resistant corrugated coaxial cable
A fire resistant corrugated coaxial cable is described that employs a high-temperature, insulating alkaline earth silicate (AES) wool dielectric. The AES wool dielectric is devoid of water as a constituent. The AES wool may be survivable under conditions of high heat, such as temperatures specified by common fire test standards (e.g., 1850? F./1010? C. for two hours). The cable is configured to maintain a relatively coaxial relation between a center conductor and an outer conductor even under aforementioned fire tests. A layer of ceramifiable silicone rubber or refractory fiber wrap can surround the outer conductor and continues to insulate it from the outside if a low-smoke zero-halogen (LSZH) jacket burns away.
COMMUNICATION CABLE
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.
