Abstract
The utility model aims to provide a fireproof anti-flaming cable. The cable includes wire cores, an inner sheath, an outer metal shielding layer, an outer fireproof filler layer, an outer sheath and a fireproof coating layer arranged from inside out successively. The wire core includes a conductor, a conductor shielding layer, an anti-flaming layer, a fireproof layer, an insulation layer, an insulation shielding layer, an inner fireproof filler layer and a metal shielding layer arranged from inside out successively. By arranging the anti-flaming layer, the fireproof layer and the fireproof filler layer outside the wire cores and by arranging fireproof filler cores among the wire cores in the inner part of the cable, anti-flaming fireproof performance of the cable is improved in the inner part of the cable. By arranging the outer fireproof filler layer, the flame retardant ceramic silicon rubber inner sheath and the fireproof coating layer in the outer part of the cable core, anti-flaming fireproof performance of the cable is improved in the outer part of the cable. By filling the gap between the cable core and the inner sheath with anti-flaming filler ropes, the anti-flaming fireproof performance of the cable is further improved. By adopting the anti-flaming fireproof structure improved from inside out, the integral anti-flaming fireproof performance of the cable is improved substantially.
