1 100% back-twist stranding: Adopt fully gear back-twist, which can realize 100% back-twist stranding.

 2 Good rigidity and high strength: Adopt fully gear back-twist, a thick wall seamless steel tube main shaft, casting iron gearbox, transmission gear processed by grinding treatment, casting iron capstan, ground shaft and gearbox transmission instead of link or belt transmission. These designs highly increase the rigidness of stranding cage, the strength of transmission system.

 3 Synchronous stranding function: According to different stranding requirements, the cages with different bobbins can combine freely. Every cage can set with synchronous pipe to strand more wires, which realize the multifunction of one machine.

 4 Accurate synchronization of ground shaft transmission: Once the gear ratio of gearbox is set, the strict proportional relation between cage rotating speed and the haul-off speed is fixed and the stranding pitch would never change in the course of starting, running and stop of machine, which ensure the accurate synchronization of every cage and easy-operated electric control system.
