The invention discloses a fireproof cable and a production process thereof. The fireproof cable comprises a cable core and a metal band, the metal band is coated outside the cable core, the cable core comprises a fire-resistant insulation wire core and an inorganic fire-resistant band which is wrapped on the outer surface of the insulation wire core, the insulation wire core is a single or a plurality of intertwisted insulation wire cores, each insulation wire core includes a conductor and an insulation layer, the fire-resistant insulation layer of each insulation wire core is a magnetization silica gel which is extruded on the outside of the conductor, and the metal band is non-magnetic. According to the fireproof cable, the magnetization silica gel is used as the insulation layer, the insulation layer can achieve insulation and simultaneously has an excellent fire resistance, the temperature resistant grade of the insulation layer can reach to 200 DEG C, and namely the cable can operate for a long time at the high temperature of 200 DEG C. The fireproof cable has the advantages that the excellent insulating property and fireproof performance can be achieved, once a building is on fire, the cable insulation layer is magnetized and encrusted in flame of 950 DEG C, the cable structure is stable, the insulating property of the cable is guaranteed at the high temperature, the cable can be continuously powered on even through the building is on fire, and simultaneously the fireproof cable is softer and more convenient to lay and install than other fireproof cables.
