Stranded Loose Tube Non-armored Cable (GYTA)Description GYTA is a stranded loose tube non-armored cable applied in duct installation.The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a PE sheath.Characteristics1.High mechanincal and temperature performance2. High strength loose tube that is hydrolysis resistant3.Special tube filling compound ensures a critical protection of fiber4.Specially-designed compact structure is good at preventing loose tubes from shrinking5.PE  sheath protects cable from ultraviolet radiation6.The following measures are take to ensure the cable watertight:         steel wire used as the central strength member,         loose tube filling compound,         100% cable core filling, and         APL moisture barrierCable Structure Standards
