Abstract: A multicore cable is composed of a bunched core composed of a plurality of electric wires laid together, each including a conductor, and an electrical insulating member provided over a periphery of the conductor, an abrasion suppressing layer configured as a taping member helically wrapped around a periphery of the bunched core, a shielding layer composed of a braided shield provided over an outer periphery of the abrasion suppressing layer, and a sheath provided over a periphery of the shielding layer. An opposite surface of the taping member constituting the abrasion suppressing layer to the bunched core and an opposite surface of the taping member constituting the abrasion suppressing layer to the shielding layer are composed of a fluoropolymer resin. The taping member constituting the abrasion suppressing layer is non-adhesively lap wound in such a manner as to partially overlap itself in a width direction thereof.

Abstract: A cable is composed of a cable core including one or more electric wires, a shield layer covering around the cable core, and a sheath covering around the shield layer. The shield layer includes a braided shield braided in such a manner that first metal wires composed of aluminum or an aluminum alloy intersect with second metal wires composed of copper or a copper alloy. An outer diameter of each of the second metal wires is larger than an outer diameter of each of the first metal wires.

Abstract: A high frequency signal transmission cable includes a conductor, an insulator provided over a periphery of the conductor, a plating layer provided over a periphery of the insulator, and a sheath provided over a periphery of the plating layer. A crack suppressing layer includes a non-cross-linked polyethylene is provided between the insulator and the plating layer, in such a manner as to remain in contact with the insulator while being provided with the plating layer over an entire periphery of a roughened outer surface of the crack suppressing layer. The crack suppressing layer is unadhered to the insulator. The plating layer is adhered to the crack suppressing layer. The crack suppressing layer suppresses an occurrence of a cracking in the plating layer by bending together with the plating layer while being integral and moving with the plating layer in a longitudinal direction of the cable.
