DISINTEGRATING BINDERS FOR MULTI-MEMBER CABLE
A multi-member cable includes at least a first cable element and a second cable element. The first and second cable elements may extend in parallel, be stranded in a helical winding pattern, or be stranded in a reverse-oscillatory winding pattern, along the length of the cable. At least one binder is helically wrapped about the first and second cable elements to hold them together. The binder is formed of a material which disintegrates when exposed to a particular liquid or heat. In a preferred embodiment, the binder may be formed of polyvinyl-alcohol (PVA).

Coaxial cable
To provide a coaxial cable with a favorable appearance and excellent processability. The above-described problem is solved by a coaxial cable comprising a center conductor (11), an insulator (12) provided on an outer periphery of the center conductor (11), an external conductor (13, 14) provided on an outer periphery of the insulator (12), and an outer coated body (15, 16) covering the external conductor (13, 14). The external conductor (13, 14) is constituted by a lateral winding shield (13) provided with metal fine wires laterally wound on the outer periphery of the insulator (12), and a metal resin tape (14) wound in a layer on the lateral winding shield (13) with a metal layer side being on an inside. The outer coated body (15, 16) is constituted by a resin tape (15) wound on the metal resin tape (14), and an extruded sheath (16) covering the resin tape (15). Given T1 as a thickness of the metal resin tape (14) and T2 as a thickness of the resin tape (15), T2/T1 is within a range from 0.180 to 0.800.

Helically insulated twinax cable systems and methods
A helically wound insulated twinax cable reduces cable dielectric loss by increasing the percentage of air in the dielectric filler surrounding the signal conductors. The helical insulator wire winding further provides mechanical support and reduces the risk of creating an electrical short-circuit. This will improve differential signaling capability of the two-conductor cable and enable longer cable range.
