The invention relates to a sheath extrusion device for an optical cable production line, which comprises a base, wherein a filling mechanism is arranged on the base, an auxiliary mechanism is arranged below the filling mechanism, the filling mechanism comprises a storage. The invention relates to a sheath extrusion device for an optical cable production line, which comprises a base, wherein a filling mechanism is arranged on the base, an auxiliary mechanism is arranged below the filling mechanism, the filling mechanism comprises a storage. An optical cable extrusion production line, commonly referred to as an extrusion line or sheathing line, is an industrial production system that uses an extrusion molding process to tightly coat one or multiple layers of polymer sheath onto the cable core (the component where the optical fibers. There are many types of defects, and common cable surface defects include pores, pinholes, bubbles, etc. They will have a certain impact on the insulation performance, mechanical properties, thermal stability and aging performance of the cable. This will cause a decrease in product qualification. Setting up an optical cable sheath extrusion line is a critical step in manufacturing robust optical cables designed to withstand environmental stress and ensure reliable signal transmission. For telecom project managers, production leaders, and factory investors, understanding the processes and. Servet Sefünc has been Product Group Manager of Sheath Extrusion at the Windsbach plant since 2017. The certified industrial foreman (plastics/rubber) has been employed at HELUKABEL for more than 20 years. How do cables actually get their individual colour? The colour concentrate in the desired. The sheathing process is where you apply the final touch to your loose tube fiber optic cable. Mechanical properties for different cable types are set with armoring and strength members.
