Beschreibung
Zusammenfassung:	A heat detection line includes a twisted pair wire composed of a pair of heat detecting wires being twisted together. 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. A melting point of the insulator of the heat detection line is lower than a melting point of an insulator of each of the plurality of electric wires.
