摘要： A foamed-polyolefin-insulated wire having a conductor diameter of 0.4 mm or less and an insulation thickness of 0.8 mm or less and satisfying, an equivalent dielectric constant less than 1.6, the fluctuation limits of the equivalent dielectric constant less than or equal to ±0.1, and conductor stripping force greater than or equal to 100 g/50 mm. Polyolefin including 10 weight % or more of an ionomer is used. Polyolefin having a swelling ratio of 55 % or more is extruded over the conductor to form a foamed insulation layer with a foaming degree of 50 % or more using a chemical foaming agent and/or an inert gas. The wire is suitable for high-speed data transmission.

摘要： The present invention relates to a data transmission cable and the like including a structure reducing the frequency dependence of cable attenuation in digital transmission, thereby suppressing signal distortions. The data transmission cable includes at least a pair of conductors, each coated with an insulator, extending along a predetermined direction; and a shield tape, provided so as to surround the conductors, including a metal layer. In particular, in the shield tape, the metal layer has a thickness of 1 &mgr;m or more but 10 &mgr;m or less, preferably 2 &mgr;m or more but 6 &mgr;m or less.

摘要： It is intended to provide a high-speed differential signal cable having a small diameter and high strength. A 4-conductor cable includes four insulation-coated insulated wires (center conductors) bundled together, and a wire mesh and an insulating sheath which cover a periphery thereof, and this cable is characterized in that a conductor size of center conductor wires is thinned so as to satisfy a specified value of attenuation with a cable length of 2.5 m, and also twisted pair wires are replaced by a quad-structure wire, so that the outer diameter is not larger than 3 mm.
