400/1+12 Durable and Advanced Tubular Stranding Machine for High-Performance Cable Manufacturing

​Tubular Strander Parameters & Introduction​

​1. Introduction to Tubular Strander​

A tubular strander is a specialized machine used in the wire and cable manufacturing industry to twist multiple wires or conductors into a compact, helical structure. Unlike planetary stranders, which use a rotational and orbital motion, tubular stranders employ a ​linear or rotational movement around a central axis, resulting in a ​tubular or layered stranding pattern. This method is ideal for producing cables with ​high flexibility, durability, and uniformity, making it suitable for a wide range of applications.

Tubular stranders are commonly used in the production of:

• ​Power cables​ (medium and high voltage)
• ​Control and instrumentation cables​
• ​Communication cables​ (coaxial, twisted pair)
• ​Specialty cables​ (submarine, mining, aerospace)

​2. Key Parameters of a Tubular Strander​

The performance and capabilities of a tubular strander are determined by several critical parameters. These parameters influence the machine's efficiency, flexibility, and suitability for specific applications. Below are the key parameters:

​3. Types of Tubular Stranders​

Based on application and automation level, tubular stranders can be categorized into:

1. ​Manual Tubular Strander​

   • Basic model with manual adjustments.
   • Suitable for small-scale production or prototyping.

2. ​Semi-Automatic Tubular Strander​

   • Features programmable lay length and speed but requires operator supervision.
   • Ideal for medium-scale production.

3. ​Fully Automatic Tubular Strander​

   • CNC-controlled with real-time monitoring and advanced tension control.
   • Best for high-volume production with consistent quality.

4. ​High-Speed Tubular Strander​

   • Optimized for rapid production with advanced cooling and tension systems.
   • Suitable for large-scale industrial applications.

5. ​Compact Tubular Strander​

   • Space-saving design for small workshops or limited production spaces.
