When it comes to manufacturing high-quality cables, stranding machines play a crucial role in twisting multiple wires into a single, durable conductor. Whether for power transmission, telecommunications, or industrial applications, choosing the right stranding machine ensures efficiency and consistency.
In this guide, we’ll explore four essential types of cable stranding machines:
- Rigid Type
- Tubular Type
- Skip Type
- Planetary Type
By understanding their differences, you can select the best machine for your production needs.
1. Rigid Stranding Machine
The Rigid type is designed for producing rigid, high-strength stranded conductors. It’s commonly used for overhead power transmission cables, ACSR (Aluminum Conductor Steel Reinforced) cables, and bare copper conductors.
Key Features:
- High-speed stranding with precise tension control
- Suitable for large-diameter conductors
- Robust construction for heavy-duty applications
Best For:
Power utilities and manufacturers needing durable, non-flexible stranded cables.
2. Tubular Stranding Machine
The Tubular type is ideal for producing flexible stranded wires and ropes. It uses a rotating tubular frame to twist wires uniformly, ensuring smooth, high-quality stranding.
Key Features:
- Multiple bobbins for simultaneous wire feeding
- Adjustable twisting speed for different cable types
- Minimal wire deformation due to controlled tension
Best For:
Telecommunication cables, automotive wires, and flexible electrical conductors.
3. Skip Type Stranding Machine
The Skip Type is known for its high-speed production and efficiency. It twists wires in two directions simultaneously, reducing production time.
Key Features:
- Faster than single-twist machines
- Compact design, saving floor space
- Suitable for fine and medium-sized conductors
Best For:
Manufacturers of control cables, data cables, and small-diameter stranded wires.
4. Planetary Type Stranding Machine
The Planetary Type is a versatile and precise machine used for stranding multiple layers of wires around a central core. It’s widely used in high-performance cable production.
Key Features:
- Multiple rotating bobbins for complex stranding patterns
- Excellent for concentric stranded conductors
- High precision with minimal wire breakage
Best For:
High-voltage power cables, submarine cables, and specialty cables requiring multi-layer stranding.
Which Cable Stranding Machine is Right for You?
Choosing the right stranding machine depends on:
✅ Cable type (rigid, flexible, multi-core)
✅ Production speed requirements
✅ Wire diameter and material
- Need rigid, high-strength cables? → Rigid type
- Producing flexible wires? → Tubular type
- Looking for fast, efficient stranding? → Skip Type
- Require multi-layer precision? → Planetary Type
Final Thoughts
Investing in the right cable stranding machine improves efficiency, reduces waste, and ensures high-quality cable production. Whether you’re manufacturing power cables, telecom wires, or industrial ropes, understanding these four machine types helps optimize your production line.
