Description
In OMC’s 144F&288F Stranded Loose Tube Double Sheath Armored (GYFTY53) PE cable, A FRP (sometimes sheathed with polyethylene (PE)) locates in the center of core as a metallic strength member. Single-mode/multimode Fiber are positioned in the loose tube, which is made of PBT materials and filled with filling compound. The tubes (and fillers) are stranded around the strength member into a compact and circular core. A Water blocking tap+A thin polyethylene (PE) inner sheath is applied around the PBT tube. Then a corrugated steel tape armor is applied, the cable is completed with a PE outer sheath.
