At the core, a steel wire, sometimes coated with polyethylene (PE) for cables with a higher fiber count, acts as a robust metallic support. Surrounding this central strength member, the tubes (along with fillers) are intricately stranded to form a compact, circular cable core. An Aluminum Polyethylene Laminate (APL) is wrapped around this core, filled with the protective compound to safeguard against water infiltration. A thin PE inner sheath is then applied over the cable core. Following this, a PSP layer is longitudinally added above the inner sheath, and the cable is finalized with an outer PE sheath for enhanced protection.
