What Is a Rigid Stranding Line and Why It’s Vital for Copper and Aluminum Cable Manufacturing?

As global infrastructure continues to expand, the demand for high-quality electrical conductors is higher than ever. A critical technology enabling large-scale cable production is the Rigid Stranding Line, an advanced manufacturing solution designed to strand single copper or aluminum wires into compacted or non-compacted, round or sector-shaped conductors.

Ideal for producing both straight and pre-spiral conductors, the rigid stranding line offers high flexibility, efficiency, and precision in cable making for the power, energy, and industrial sectors.

 Product Overview: Rigid Stranding Lines

The Rigid Stranding Line is engineered to process single copper (Ø1.5–4.5 mm) or aluminum (Ø1.8–5.0 mm) wires into high-capacity conductors. The system can create:

• Round compacted conductors (up to 800 mm² for Cu and 1200 mm² for Al)

• Sector-shaped conductors

• Pre-spiraled compacted conductors

The line supports both standard and compact constructions, making it ideal for producing overhead, underground, or insulated power cables for low, medium, and high voltage applications.

Each stranding cage comes with:

• Automatic side or bottom loading/unloading systems

• Close die and compacting heads

• Independent parameter control and fault monitoring

The rigid line ensures that pitch remains consistent even under variable operating conditions, thanks to its synchronous electrical control system and user-friendly touchscreen interface.
