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.
