Fireproofing and highly-flexible data signal transmission cable

The utility model relates to a fireproofing and highly-flexible data signal transmission cable. At least one stranded wire pair and at least one insulated core are stranded into the cable core; a split-phase composite shielding layer and a split-phase wrapping layer are arranged at the exterior of the wire pair; a cabling wrapping layer, a high-fireproofing nanometer ceramic silicon rubber inner sheath, a total composite shielding layer, a wrapping isolation layer and a high-fireproofing nanometer ceramic silicon rubber outer sheath are sequentially arranged at the exterior of the cable core; and high-fireproofing halogen-free fillers are arranged in gaps among cable cores. The cable is good in electric property and excellent in fire resistance and anti-electromagnetic interference capacity, and can better meet the operating requirements.
