Example Embodiment
[0016] Such as figure 1 As shown, the temperature measurement flexible and fire-resistant transmission signal cable of the present invention includes a cable core, and the cable core is formed by twisting three insulated cores and an optical fiber unit; the insulated core is composed of The aluminum alloy conductor 1, the semi-conductive cloth tape 2 wrapped around the aluminum alloy conductor, and the insulating layer 3 extruded outside the semi-conductive cloth tape; the optical fiber unit is composed of an optical fiber 4 and a metal shield wrapped outside the optical fiber The layer 5 and the first glass ribbon 6 extruded outside the metal shielding layer are formed. Fill the gaps of the cable core with glass filaments 8. The cable core is extruded with a flame-retardant layer 9 with a thickness of 2.65-3.65mm, and the flame-retardant layer is extruded with a metal conductive tube 10 with a thickness of 2-4mm. An outer sheath 11 with a thickness of 3-6mm is provided; a tem...
