The utility model relates to a digital program control flexible cable for a high-flame-resistance broad band, which comprises a cable core, a belting layer of the cable core and an outer protective sleeve. The cable core is internally provided with a lead with a conductor coated with an insulation layer; the conductor of the lead is formed by a plurality of strands of tinned brass wires; and an aluminum strip shielding layer and a brass wire knitting shielding layer are sequentially arranged between the belting layer and the outer protective sleeve. The utility model has favorable flexibility, the conductor of the utility model is not easily hardened and brittled; the shielding performance of the cable is enhanced; and the utility model can be applied to the places with large electromagnetic interference, and has high flame resistant performance.
