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)
