GYTA53(Loose Sheathed Stranded Reinforced Optic Cable)

The loose tubes are made of high modulus plastics (PBT) and filled with water resistant filling gel. Loose tubes are stranded around the FRP central strength member, cable core  is filled with cable filling compound. The corrugated aluminum tape folding and polyethylene (PE) is extruded as inner sheath, then water swollen yarns and corrugated steel tape is     longitudinally applied over the inner sheath, and combined with a durable PE sheath.
