A Planetary Strander, also known as a Torsion Back Twist Machine, is specialized wire and cable machinery designed to strand multiple wires or conductors while controlling torsion and back twist during the stranding process. It helps achieve uniform construction and controlled wire tension.

Individual wires are supplied through dedicated pay-off systems and arranged around a central axis. The planetary system rotates the wire elements while the machine controls their movement and back twist to produce the required strand construction and lay length.

A Torsion Back Twist Machine is used for manufacturing suitable stranded conductors, flexible wires, cable elements, and other wire products where controlled torsion and back twist are important for the final construction.

Back twist refers to the controlled reverse rotation or torsional movement applied to individual wires during the stranding process. Proper back-twist control helps manage residual torsion and contributes to consistent strand formation.

A Torsion Back Twist Machine can provide controlled wire torsion, uniform stranding, consistent lay length, improved strand formation, reliable tension management, and efficient production for suitable wire and cable applications.

Depending on the machine configuration, Planetary Stranders can process suitable copper, aluminium, and other specified conductive wires. Wire diameter, material, number of strands, and final conductor construction should be considered during machine selection.

Yes. Depending on the machine design and specifications, Planetary Stranders can be configured for suitable aluminium wire and conductor applications.

Important factors include wire material, individual wire diameter, number of wires, central core size, finished conductor diameter, required lay length, back-twist requirements, production speed, take-up drum size, and automation requirements.

Yes. Where technically suitable, the machine can be integrated with upstream pay-off equipment and downstream processes such as compacting, taping, armouring, extrusion, take-up, or other cable-processing systems.

Yes. Depending on the wire construction and machine configuration, Torsion Back Twist Machines can be suitable for producing stranded conductors used in flexible wires and cables where controlled torsion is required.
