Description
In OMC’s 2-24F Unitube Armored Cable (GYXS&GYXTW) Glass Yarn PE, single-mode/multimode fibers are positioned in the loose tube, which is made of PBT materials and filled with filling compound. The loose tube is covered with Water-blocking Glass Yarn and Steel armored tape to guarantee the compactness and longitudinal water-blocking performance. At the same time. Two parallel steel wires are embedded in out sheath to offer high tensile.
