Equipment Purpose and Characteristics:
The optical fiber secondary coating production line is mainly used for the extrusion of optical fiber loose tube bundles with 2 to 12 cores and an outer diameter of Ф1.5 to Ф3.0mm, as well as the extrusion of optical cable filling ropes. The extrusion material should be suitable for PBT, PP, PC, and PE. The extrusion shape is round and uniform in diameter, with a smooth surface.
The machine has the following features:
The structural design speed of the production line is 600M/Min, with a production speed of ≥50 0m/min (for Ф1.80mm, wall thickness 0.30mm, PBT loose tubes).
The control range for fiber excess length is 0～3‰.
To enhance product stability and reliability, the machine's cold water circulation system adopts automatic temperature control and is equipped with a refrigeration unit. 4 . The optical fiber filling system features a constant temperature control device, ensuring precise and stable filling.
Key electrical control components used in production are all high-quality products, reliable in quality, and convenient for maintenance.
The extruder adopts a 65-type with a length-to-diameter ratio of 30:1.
