<P>PROBLEM TO BE SOLVED: To provide a heat-resistant cable for high-speed transmission that can perform the high-speed transmission of higher-capacity information than before without lowering the heat resistance of the heat-resistant cable for use in a small power circuit for fire-fighting facilities and the like. <P>SOLUTION: The heat-resistant cable for high-speed transmission has a structure in which a twisted pair wire 4 is formed of an insulating core wire 3 constituted by coating a conductor 1 with an insulator 2 formed of crosslinked polyethylene, and a bundle sheath 8 is coated on an assembled twisted wire that is formed by bundling a plurality of twisted pair wires 4. The insulator 2 has a thickness of 0.45 mm or larger, and the twisted pair wire 4 is pair-twisted at a pitch of 45 mm or smaller. <P>COPYRIGHT: (C)2010,JPO&INPIT |
