Anyone in the cable business knows that fiber optic cable manufacturing is a sophisticated optical‑mechanical‑electrical composite precision product, characterized by highly sensitive optical parameters and stringent micro‑structure tolerances. But few stop to consider that the equipment used to make those cables is itself a “precision product.”

An SZ stranding and cabling line – from a set of blueprints to a machine running day and night on the production floor – passes through countless steps. The precision of every step ultimately reflects on the customer’s line: stable tension, accurate pitch, and sufficient concentricity.

Below, from the perspective of cable equipment manufacturing, we break down the complete process of a stranding machine and a sheathing line – from design to factory release.
