Each heat detecting wire includes a conductor and an insulator covering a periphery of the conductor. The conductor is non-magnetic and composed of a copper alloy with a tensile strength of 900 MPa or more. A multi-core cable includes the heat detection line, a plurality of electric wires, and a sheath covering the heat detection line and the plurality of electric wires together.

摘要： 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.

A crack suppressing layer 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 outer surface of that crack suppressing layer. The crack suppressing layer is composed of a resin film to suppress the occurrence of a cracking in the plating layer by bending while moving in a longitudinal direction of the cable relative to a bending of the insulator.

摘要： A coaxial cable is composed of a conductor, an electrical insulating member covering a periphery of the conductor, a shield layer covering a periphery of the electrical insulating member, and a sheath covering a periphery of the shield layer. The shield layer is configured to include a lateral winding shielding portion with a plurality of metal wires being helically wrapped around the periphery of the electrical insulating member, and a batch plating portion made of a hot-dip plating covering respective peripheries of the lateral winding shielding portion. The shield layer includes an outer peripheral portion, in which the metal wires are covered with the batch plating portion, and an inner peripheral portion, in which the metal wires are not covered with the batch plating portion. The outer peripheral portion of the shield layer includes intermetallic compounds between the metal wires and the batch plating portion.
