High-flame-retardant flexible fireproof cable

The invention belongs to the technical field of cables, and particularly relates to a high-flame-retardant flexible fireproof cable. Comprising a filling layer, a protective sleeve is arranged on the outer surface of the filling layer, multiple groups of inner cavities are uniformly arrayed in the filling layer, elastic ring pipes are arranged in the inner cavities, insulating layers are arranged in the elastic ring pipes, and cable cores are arranged in the insulating layers; a center cavity is formed in the filling layer, and mounting ring sleeves are arranged at the ends of the two sides of the elastic ring pipe. The device is higher in self-adaptive adjustment capability, and the extrusion force applied to the cable core by the insulating layer is effectively ensured, so that the electrifying efficiency and the electrifying stability of the cable core are ensured; and meanwhile, the fixed-point cooling flame-retardant efficiency is better, great economic and safety losses are effectively avoided, the spli
