List of Copper Conductor and Insulated Wire Stranding Machines
In the wire and cable manufacturing process, conductor stranding and insulated wire stranding are core processes that directly affect the cable's electrical performance, mechanical strength, and flexibility. Depending on the structure, stranding machines can be categorized into tubular stranders, cage stranders, rigid bobbin stranders, and more. Details are as follows:
Bunching Machine (Buncher)A machine that twists multiple single wires or strands in the same direction and pitch to form a stranded conductor or core. Classified into single-twist and double-twist types based on the number of pitches formed per rotation.
Tubular Stranding Machine (Tubular strander)A machine that twists wires by rotating a tubular body.
The wire spool baskets float along the central axis of the tube.
Planetary Strander (Cage Stranding Machine)A machine that twists wires by rotating a cage-like structure.
Consists of one or multiple cages, with wire spool baskets symmetrically arranged around the central axis.
Rigid Bobbin Stranding Machine (Disk-Type Stranding Machine)A machine that twists wires by rotating a rigid bobbin disk.
Wire spools are mounted parallel to the central axis.
Bow-Type Strander (Skip Strander)A machine that twists wires using rotating bows aligned in a straight line.
Each bow rotates around a floating wire spool basket, used for stranding or cabling.
Rigid StranderA machine that twists wires using a rigid rotating cage without a back-twist mechanism.
Wire spool frames are fixed (non-floating).
Subtypes: Fork-type, star-type, drum-type, and frame-type.
Twinning Machine (Twinner)A machine that twists two insulated conductors together.
Pair TwisterA machine that twists two insulated conductors into a telephone cable pair.
Star Quadding Machine (Quadder)A machine that twists four insulated conductors into a star quad for communication cables.
SZ Stranding Machine (SZ Strander)A machine that alternates between left (S) and right (Z) twists, used for communication cable quads, unit stranding, and small power cable cabling.
Cross Stranding MachineA machine that changes the relative positions of insulated conductors during stranding.
Planetary CablerA machine that completes cabling by rotating a cage structure.
Wire spool baskets float around the central axis.
Drum Twister Laying-Up MachineA machine that completes cabling by rotating the take-up and traction mechanism.
