A differential signal cable includes a pair of signal line conductors for transmitting differential signals, an insulation collectively covering the pair of signal line conductors, a shielding tape wrapped around the insulation, and an insulating tape wound around the shielding tape. A gap is formed between an outer peripheral surface of the insulation and an inner surface of the shielding tape such that the insulation is movable relative to the shielding tape.

A radio head cable may include an inner conductor and an outer conductor coaxially arranged around the inner conductor. The inner conductor may have a first direct current resistance and a cross-sectional area of at least 5.0 square millimeters. The outer conductor may have a second direct current resistance equal to or less than the first direct current resistance. A first dielectric layer including polyvinylchloride may be positioned between the inner conductor and the outer conductor. A second dielectric layer including polyvinylchloride may be positioned around the outer conductor, and a third dielectric layer including nylon may be positioned around the second dielectric layer.

A cable includes a jacket, a shielding tape, a pair of wires, an inner and outer jacket layer, and a separator. The shielding tape includes a substrate and a plurality of conductive shield segments disposed on the substrate. The pair of wires form a twisted pair. The inner and outer jacket layers are extruded onto inner and outer surfaces, respectively, of the substrate. The substrate, the inner jacket layer and the outer jacket layer are bonded together into a single layer that defines a circumference. Each of the conductive shield segments: extends only partially around the circumference of the single layer; is longitudinally spaced from each longitudinally adjacent one of the conductive shield segments; is radially spaced from, and overlaps a portion of, each immediately circumferentially adjacent one of the conductive shield segments; and is embedded in at least one of the inner jacket layer and the outer jacket layer.

A cable comprising hybrid carbon nanotube (CNT) shielding includes at least one conducting wire; at least one insulating layer covering at least one of the at least one conducting wire; a metallic foil component configured for lower frequency shielding function; and a CNT tape component configured for higher frequency shielding function.

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.
