  • MULTICORE CABLE
    Publication number: 20190074110
    Abstract: A multicore cable includes a cable core formed by twisting a plurality of electric wires, a wrapping tape wrapped around the cable core, a shield member provided on an outer circumference of the wrapping tape, and a jacket coating an outer side of the shield member. The wrapping tape has a tape resin layer which has a tensile strength of 300 MPa or more and has a property of not melting or decomposing at 300° C., and the jacket is formed of fluororesin extrusion-molded for coating.

  • Opto-electro hybrid cable having electronic wires and optical fibers
    Patent number: 8818153
    Abstract: According to the opto-electro hybrid cable of the invention, it is possible to prevent the excessive lateral pressure from being applied to the optical fibers from the electronic wires and the excessive bending or twisting from being generated. In addition, it is possible to increase the tensile strength and to prevent the excessive tension from being applied to the optical fibers, so that it is possible to keep the favorable transmission characteristics.
