Abstract
The utility model discloses a fireproof cable which includes a plurality of cable cores. A filling layer is arranged among the cable cores and a protective layer is arranged externally. The filling layer is filled with an inorganic heat absorption material which can absorb heat and release steam when being heated. The inorganic heat absorption material of the fireproof cable can release the steam when being heated to a certain degree. The inorganic heat absorption material is subjected to a heat absorption process during a steam releasing process, wherein the heat absorption process itself has a cooling effect. In addition, the heat can be taken away continuously due to evaporation of the steam so that temperature of the cable is decreased, thereby improving fireproof performance of the cable, improving a continuous power supply capability and prolonging a continuous power supply time of the cable in a fire hazard.
