The utility model relates to the technical field of cables, in particular to a fire-resistant halogen-free low-smoke flame-retardant cable, which comprises a main cable core, an insulating sleeve is sleeved on the outer wall of the main cable core, a plurality of groups of auxiliary cables are arranged on the inner circumference of the insulating sleeve, a heat insulation layer A is arranged outside the insulating sleeve, a heat absorption layer is arranged outside a reinforcing layer, and a heat insulation layer B is arranged outside the heat absorption layer. A heat insulation layer B is arranged outside the waterproof layer, and a flame-retardant layer is arranged outside the heat insulation layer B. The heat insulation layer B, the heat insulation layer A and the heat absorption layer are matched to reduce the temperature transmitted to the main cable core and the auxiliary cable core, and heat conduction columns are arranged to uniformly transmit the temperature borne by the heat absorption layer to the
