Abstract

The invention discloses a loose-tube layer-stranded optical cable and its cable-forming device and cable-forming process. The loose-tube layer-stranded optical cable includes a central strengthening unit and a plurality of loose tubes evenly arranged on the outer periphery of the central strengthening unit. , the surface of the central reinforcing element is evenly sprayed with glue, and then bonded with all the loose tubes and then twisted, and a dry water-blocking material is arranged between the central reinforcing element and the loose tubes. The present invention does not need tying yarn or uses 1 to 2 tying yarns, can also ensure the stability of the cable core structure and other performances, has high production efficiency, is not easy to pull the cable, and can improve product quality and yield.

Description

technical field [0001] The invention belongs to the technical field of optical communication transmission, and in particular relates to a loose-tube stranded optical cable, a cable-forming device and a cable-forming process. Background technique [0002] Most of the existing loose-tube stranded optical cables are cabled by twisting and binding the cable core with a high-speed yarn binding machine to keep the cable core structure stable. The binding pitch is generally between 20mm-28mm, and the number of TURNS is between 6 and 8. Due to the fixed speed of the binding machine, the speed of the cable production line is restricted, and the cable forming process becomes the bottleneck process in the production of optical cables. At the same time, due to the wear and tear on the path, guide wheel, and plate after binding the yarn and the cable core after binding the yarn, it is easy to cause the yarn to split, fluff or even break the yarn, and the cable core is easy to be broken d...
