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.
