Rosendahl’s unique SZ stranding technology is designed to manufacture fiber optic cables for a wide range of indoor and outdoor applications with a flexible layout.

The stranding technology supports the stranding of jelly-filled as well as complete dry cable designs.
Stranding can be done either as a stand-alone process or tandemized with the jacketing process.
Advanced new technical solutions like torsion shaft lay-plate SZ stranding machines, dual cross binders with an adequate line control system enable a controlled stranding process.

Each single stranding disc is individually driven via a timing belt without intermediate gear.
The stranding process guarantees in all circumstances low stranding tension fluctuation, accurate and stable lay length and constant binding tension.
