G652D Fiber Cable

30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and sale optical fiber cable to more than 30 countries and have 18 years` rich experience to export cables .

**Influence of Cable Extrusion Process Parameters on Finished Product Quality**

Temperature is a fundamental parameter affecting sheath quality. Increasing the temperature can improve surface quality and mechanical properties, but thermal degradation must be avoided. At the same time, temperature indirectly affects the fiber excess length through thermal expansion effects, which must be incorporated into an integrated control system.

Excess length control is the core challenge in cable extrusion. In central loose tube cables, multiple factors-including the pay-off tension of steel wires/loose tubes, the resistance from steel tape longitudinal wrapping, and the shrinkage of sheath materials-jointly determine the sign and magnitude of secondary excess length. Understanding the direction of influence of each factor (positive/negative effects) is a prerequisite for effective control.

Extrusion speed has a nonlinear relationship with outer diameter stability. A segmented compensation strategy is required to eliminate deviations and ensure that the finished product meets geometric dimension specifications.

Mould design determines the molding quality of profiled sheaths. The roundness deviation and indentation defects of GFRP-embedded sheaths are directly related to the design of the GFRP hole center distance. A bending coefficient should be introduced for pre-compensation design.

There is deep coupling among the various process parameters. Isolated parameter optimization struggles to achieve optimal results. A multi-parameter collaborative control strategy must be established, combined with online monitoring to achieve closed-loop regulation.
