Manufacturing method of fire-resistant cable

The invention discloses a manufacturing method of a fire-resistant cable, and the method comprises the following steps: 1, performing the wrapping of a conductor through a wrapping machine to form a wrapping layer, extruding an insulating layer by a plastic extruding machine, and wrapping the insulating layer on the wrapping layer to obtain one or more cable cores; 2, stripping the heads of one ormore cable cores, and exposing the conductor in each cable core in the air; 3, connecting with one or more conductors exposed in the air by adopting a pull wire; 4, enabling the pull wire to pass through a plastic extruding machine and a cable traction machine, and enabling one or more cable cores to move under the traction of the cable traction machine; 5, carrying out extrusion molding on the one or more movable cable cores through the plastic extrusion machine to form a sheath wrapping one or more cable cores so as to form the cable. The method has the advantage that the wrapping layer andthe insulating layer can
