摘要： A fire resistant coaxial cable and method of making is described that has a 2-part dielectric made of a polymer foam and a ceramifiable silicone rubber. The polymer foam, which can be polypropylene or other polymers, leaves little-to-no residue in the cable that causes electromagnetic loss when upon burning. The polymer foam can be extruded over a center conductor using an inert gas, such as nitrogen, to propagate the foam, ensuring little-to-no residue in the cable. The ceramifiable silicone rubber can be extruded over the polymer foam. The ceramifiable silicone rubber can have a polysiloxane matrix with inorganic flux and refractory particles that ceramify under 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. Another layer of ceramifiable silicone rubber surrounds the outer conductor and continues to insulate it from the outside if a low-smoke zero-halogen (LSZH) jacket burns away.

摘要： Methods of testing and installing fire-resistant coaxial cables are described. The dielectric between the coax cable's central conductor and outer coaxial conductor ceramify under high heat, such as those specified by common fire test standards (e.g., 1850° F./1010° C. for two hours). The dielectric can be composed of ceramifiable silicone rubber, such as that having a polysiloxane matrix with inorganic flux and refractory particles. Because thick layers of uncured ceramifiable silicone rubber deform under their own weight when curing, multiple thinner layers are coated and serially cured in order to build up the required thickness. A sacrificial sheath mold is used to hold each layer of uncured ceramifiable silicone rubber in place around the central conductor while curing. The outer conductor can be a metal foil, metal braid, and/or corrugated metal. Another layer of extruded ceramifiable silicone dielectric or an outer wrap of ceramic fiber yarn surrounds the outer conductor and continues to insulate it from the outside if a low smoke zero halogen jacket burns away.

摘要： A coaxial cable and method of construction thereof are provided. The coaxial cable includes an elongate central conductive member; a dielectric insulative layer encasing the central conductive member; an outer protective sheath, and a braided EMI shield layer including hybrid yarn sandwiched between the dielectric insulative layer and the outer protective sheath. The hybrid yarn includes an elongate nonconductive filament and an elongate continuous conductive wire filament. The wire filament is interlaced in electrical communication with itself or other wire filaments along a length of the EMI shield layer to provide protection to the central conductive member against at least one of EMI, RFI or ESD. The method includes providing a central conductive member; forming a dielectric insulative layer surrounding the central conductive member; braiding an EMI shield layer including hybrid yarn about the insulative layer, and forming an outer protective sheath about the braided EMI shield layer.

摘要： The present invention comprises a shielding tape comprising at least one shielding layer, at least one separator layer, a first (inner) edge, and a second (outer) edge. The shielding tape further includes an indicator extending along at least a portion of the outer edge. The indicator is for identifying the outer edge when the outer edge overlaps the inner edge when the shielding tape is positioned onto a cable. Alternatively, both edges may have an indicator. The present invention makes it easy to locate the outer edge of the shielding tape for an installer wishing to remove at least some of the shielding tape before crimping or compressing a connector onto the end of a cable.

摘要： A coaxial audio cable is provided having a core, braided inner and outer conductors, dielectric layer between the inner and outer conductor and a jacket surrounding the outer conductor. The inner conductor is disposed around the core at a braid angle of approximately eighteen degrees. The dielectric layer is wrapped around the braided inner conductor.

摘要： A method of producing a leakage graded coaxial cable having a braided shield, in which ends of the shield wire are dropped as braiding progresses. Gaps in the shield having progressively increasing size are produced through which the radio frequency field leakage occurs, which facilitates providing a constant radio frequency field around the cable. The cable is coated with a jell flooding agent prior to extrusion of its protection jacket, which fills the interstices and gaps of the shield, and solidifies to a waxy, semi-resilient consistency. The resulting cable can be coiled and flexed, maintaining its shield reliability, and rejects water and fluids in case pinholes in the jacket occur.
