What Is a Tubular Stranding Machine? A Tubular Stranding Machine is a type of cable-making equipment designed to strand multiple wires together into a cohesive, structured conductor. Unlike rigid stranders where bobbins are stationary, tubular stranders feature rotating spindles inside a tubular structure that spins at high speed, offering greater flexibility and speed for small to medium-sized wires. This machine is ideal for manufacturing: Copper and aluminum stranded conductors Steel wire armoring Overhead ground wires Control cables and signaling wires ACSR (Aluminum Conductor Steel Reinforced) cables Core Features High Rotational Speed: Tubular design allows speeds up to 1,000 RPM, ideal for fine wire stranding. Flexible Configurations: Available in multiple spindle setups (6, 12, 18, or 24 bobbins) to match production needs. Central Steel Core Integration: Supports stranding around a central steel wire for reinforced cable types like ACSR. Precision Control System: Equipped with PLC and touchscreen interface for parameter setting, pitch control, and fault detection. Stable Tension Control: Advanced tension mechanisms ensure consistent winding and conductor integrity. Robust Safety Enclosures: Fully enclosed rotating tubes with safety interlocks to protect operators. Applications Across Industries The Tubular Stranding Machine is widely used in the production of: Power Transmission Cables ACSR Overhead Conductors Steel Wire Armored Cables Communication and Data Cables Industrial Control Cables Grounding and Earth Wires Its ability to strand conductors with or without steel reinforcement makes it suitable for both electrical and mechanical applications.

Rigid Stranding Machine – Applications Overview   A Rigid Stranding Machine is a key piece of equipment in the cable manufacturing industry, primarily used to strand single copper or aluminum wires into conductors with round, sector-shaped, or pre-spiraled cross-sections. These machines are essential for producing high-capacity power cables used in various energy transmission and distribution systems.   Main Applications of Rigid Stranding Machines 1. Power Transmission & Distribution Cables Low, medium, and high voltage cables require stranded conductors for flexibility, strength, and current-carrying capacity. Rigid stranders are used to produce compacted and non-compacted round or sector-shaped conductors for both underground and overhead power lines. 2. Milliken Conductors Rigid stranding machines are used to assemble segmented copper conductors (Milliken type) for extra-high voltage (EHV) and high voltage (HV) AC transmission cables, improving skin effect performance and load capacity. 3. Renewable Energy Infrastructure Wind farms, solar plants, and hydropower stations require heavy-duty aluminum or copper conductors for long-distance power transmission. Rigid stranders help manufacture these conductor cores efficiently. 4. Utility and Grid Modernization Projects Modern smart grids require pre-spiraled and sector-shaped conductors for better space utilization and reduced losses. Rigid stranding machines help produce the core conductors needed for grid upgrades. 5. Submarine & Subterranean Cables For subsea or underground cable applications, compact and high-density stranded conductors are crucial. Rigid stranders provide the strength and dimensional accuracy needed for such demanding installations. 6. Industrial Cable Manufacturing Used in the production of industrial control cables, mining cables, and railway signaling cables, where custom conductor profiles and consistent stranding pitch are required.  Why Rigid Stranding Machines Are Preferred: High precision and consistency in conductor geometry Support for large conductor cross-sections (up to 1200 mm²) Capability to produce both standard and compacted strands Automation for tension control, bobbin handling, and pitch adjustment Suitable for continuous, high-volume production

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.

As global demand for high voltage (HV) and extra-high voltage (EHV) power cables continues to rise, manufacturers are turning to more efficient, high-precision solutions to keep up with market needs. One of the most essential technologies enabling this production is the High Speed Concentric Stranding Line — a specialized cable-making machine designed for producing both overhead and insulated AC/DC power conductors with high precision and productivity.    What Is a High Speed Concentric Stranding Line? A High Speed Concentric Stranding Line is an advanced cable manufacturing system designed for the stranding of large copper or aluminum conductors, including Milliken and compacted round or trapezoidal wires. It is widely used in the production of high voltage (HV) and extra-high voltage (EHV) cables that power critical energy infrastructure across the globe. The stranding process uses a no-back-twist concentric method, ensuring excellent conductor alignment, reduced cable deformation, and improved current-carrying capacity — essential for long-distance and high-load power transmission.  Key Features: Application: Suitable for AC cables using Milliken conductors and DC cables with large round or trapezoidal compacted conductors Cage Speed: Up to 500 RPM Stranding Pitch: 40–350mm (Stepless adjustable) Stranding Structure: Concentric design with front & rear support, flying wing system, wire separation, and bobbin storage Motorization: Each component (cage, storage bobbin, traverse system) driven by independent variable frequency motors Wire Rewinding: Individual wires rewound to bobbins via external payoff system with separate motorized traverse  Key Advantages: High Efficiency with Minimal Centrifugal Force Thanks to the concentric cage structure, the rotation center aligns with each bobbin’s center, minimizing centrifugal force and allowing for higher rotational speeds and faster stranding. Large Capacity Bobbin Storage Reduces the frequency of loading/unloading, significantly lowering labor intensity and increasing uptime. Streamlined Wire Handling Once the storage bobbin is emptied, single wire can be rewound directly from the drawing process, minimizing intermediate steps and saving time. Stable and Adjustable Tension Cage tension is independent of cage speed, offering precise control during the entire stranding process. Low Maintenance Design With fewer wear-prone components and a compact mechanical structure, the system ensures long-term reliability and reduced maintenance costs.
