The utility model discloses a high-temperature-resistant aluminum-plastic composite belt for a rail transit power cable. The ceramic fiber composite material comprises an inner layer, a contact layeris welded to the top of the inner layer, the contact layer comprises a heat insulation layer, a filling layer and ceramic fibers, the top of the inner layer is connected with the bottom of the heat insulation layer in a welded mode, the top of the heat insulation layer is connected with the bottom of the filling layer in a welded mode, and the top of the filling layer is connected with the bottomsof the ceramic fibers in a welded mode. The heat insulation layer in the contact layer plays a role in high temperature resistance, damage to the aluminum-plastic composite belt due to over-high internal temperature is prevented, use of the cable is guaranteed, meanwhile, the contact layer blocks the internal temperature, spontaneous combustion caused by over-high temperature is avoided, and theavailable requirement is gu
