Cabling method for special-shaped cable core

The invention provides a cabling method for a special-shaped cable core. During an extrusion molding process, a special-shaped cabling tray is adopted to perform tray loading; the end of the special-shaped cabling tray is connected with that of a tray iron chain; a cabling front end is towed by the iron chain, and the length of the iron chain is from a cabling twisting closer to a cabling traction wheel; the iron chain serving as a traction rope is connected with the head end of a cabling cable core; a stranding cage of a cabling machine adopts non-back-twist stranding; after the end of the cable core arrives at a take-up reel, the pulling chain is removed; the cable core is loaded onto the take-up reel so as to be wound up till the tail end of the cable; the machine is stopped, a special cabling tray iron chain disk brake device for special-shaped cables is regulated; the stranding cage of the cabling machine adopts non-back-twist stranding, and the exterior of the cable core is wrapped and tied by use of a
