摘要： A communications cable is provided that includes a pair of twisted pair of wires, each coated with a fluoropolymer insulator. The twisted pair of wires is configured to carry a differential signal, such as a differential data signal and/or a differential power signal. The fluoropolymers are highly effective insulators and significantly reduce both the effects of internal and external electromagnetic interference while maintaining low cable attenuation, even when operating within a temperature range of-40° C. to 150° C.

摘要： A fire resistant cable includes cable at least one conductor and at least one mica layer surrounding the at least one conductors. The fire resistant cable further includes a first layer of insulation surrounding the at least one mica layer and a second layer of insulation surrounding the first layer of insulation. The first and second layers of insulation are made of a composition based on a flame retardant ceramifiable silicone rubber. The second layer of insulation further contains a reinforcement material.

摘要： A fire resistant coaxial cable and method of making includes 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： Elastomer compositions with high dielectric constants are disclosed. Embodiments of the disclosure include a high dielectric constant (high-K) elastomeric composition comprising an elastomer, carbon black (CB), and organoclay (OC). The composition is not dependent on any raw material with inherent high-k or any metal oxide type material that changes conductivity with applied voltages. The composition instead uses distributed electric fields and polarizability with carbon black and organoclays. This allows for a high-k material through polarizability with limited large-scale electron sharing.

摘要： In accordance with example embodiments of the present disclosure, the invention allows effective sending and receiving of radio signals commonly associated with those sent and received by antennas. The utility of the invention includes a versatile antenna wire comprised of an embedded formed electrical conductor within a protective, non-electrically conductive sheath or structural element that facilitates shorter-than-typical antenna designs. The versatile antenna wire can facilitate antenna radiators that are up to 80 percent shorter than traditional wire radiators—while still providing exceptional operating characteristics. In some embodiments, the antenna wire is a specifically contoured conductive material. Electrically conductive material may be wire; metalized tape; metalized foil; electrically conductive polymer; or conductive ink or coating.

摘要： It is aimed to suppress the peeling of an adhesive from an insulation coating of an insulated electrical cable due to resin shrink after the molding of a molded member. A molded part-equipped electrical cable includes a terminal-equipped electrical cable with an insulated electrical cable and a terminal, an adhesive provided on a surface of the insulation coating of the terminal-equipped electrical cable and a molded member covering from a part provided with the adhesive on the insulation coating of the terminal-equipped electrical cable to a connected part of the insulated electrical cable and the terminal. The molded member includes a first molded part and a second molded part separately molded, and the first molded part includes a part covering the adhesive while being in contact with the adhesive.

摘要： A composition for an electric wire coating material that has excellent damage resistance, low-temperature flexibility, and tear resistance, and an insulated electric wire in which this composition is used. The composition for an electric wire coating material containing polyvinyl chloride contains a plasticizer in an amount of 15 to 30 parts by mass and a thermoplastic polyurethane elastomer in an amount of 0.01 to 10 parts by mass, with respect to 100 parts by mass of the polyvinyl chloride. An insulated electric wire is obtained by coating an outer circumference of a conductor with an insulating coating layer, using this composition for an electric wire coating material in an electric wire coating material.
