Flexible type mineral insulated fireproof cable

Disclosed is a flexible type mineral insulated fireproof cable, which belongs to the technical field of cable protection. The flexible type mineral insulated fireproof cable includes four cable cores arranged in an annular array; 3 fireproof mica layer is wrapped outside the cable core; an insulating layer is wrapped outside the fireproof mica layer; an armor layer is sleeved outside the insulating layer; an 1oxygen barrier layer is wrapped outside the four cable cores; and four carbon dioxide filling layers are filled in a cavity between the oxygen barrier layer and the cable core. According to the insulated fireproof cable provided by the present invention, an insulating layer and a fireproof mica layer are wrapped outside a cable core; when the cable is used, a copper core heats, and the fireproof mica layer has good insulation performance and heat resistance; an armor layer is wound on an outer wall of the insulating layer, so that a mechanical strength of the cable can be effectively increased, and an erosion resistance can be improved; and an oxygen barrier layer and an isolation layer that are provided can take effective fireproof and obstruction effect, and effectively control an external fire behavior, thus further protecting the cable.
