Carbon fiber reinforced cold-resistant temperature self-measurement cable

The invention relates to a carbon fiber reinforced cold-resistant temperature self-measurement cable which comprises carbon fiber conductors, insulating layers, an inner cushion layer, an outer sheath and an outer protection layer, wherein each carbon fiber conductor is externally wrapped with one insulating layer to form a cable core; a plurality of cable cores are tightly wrapped by the inner cushion layer; the outer sheath is arranged outside the inner cushion layer; the outer protection layer is arranged outside the outer sheath; a carbon fiber reinforced core is arranged in a gap surrounded by the cable cores; an optical unit is arranged in a gap between the cable cores and the inner cushion layer, and comprises a plurality of optical fibers; and at least one optical fiber is a grating optical fiber inscribed with a temperature measurement grating. The cable has the beneficial effects that the strength is high; a certain cold-resistant effect can be exerted; communication is available; and the temperature of the cable can be monitored in real time.
