High-strength light fireproof cable

The utility model relates to the technical field of cables, in particular to a high-strength light fireproof cable, which comprises a cable core, an insulating layer, a belting layer and a heat insulation layer are sequentially sleeved outside the cable core, supports are arranged on the periphery of the outer side of the heat insulation layer, each support is of a hollow structure, and connecting pipes are communicated among a plurality of sets of supports. According to the utility model, the refractory mortar layer arranged in the support and the connecting pipe is heated and hardened in case of a fire to form a high-strength fire retardant layer, so that effective fire prevention of the cable core in the cable is realized, the fire resistance of the cable is enhanced, the cable can provide long-time protection in case of the fire, and the service life of the cable is prolonged. And meanwhile, in order to enhance the heat dissipation performance of the inner side of the connecting pipe, heat conducting fins
