Stranded Loose Tube Light-armored Cable ( GYTS )

FlyingFiber’s GYTS stranded loose tube light-armored cable provide 250μm fibers, 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. The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.

1). Good mechanical and temperature performance.

2). High strength looes tube that is hydrolysis resistant.

3). Special tube filling compound ensure a critical protection of fiber.

4). Specially designed compact structure is good at preventing loose tubes from shrinking.

5). Crush resistance and flexibility.

6). PE sheath protects cable from ultraviolet radiation.

7). The following measures are taken to ensure the cable watertight:

– Steel wire used as the central strength member.

– Loose tube filling compound.

– 100% cable core filling.

– PSP enhancing moisture-proof.

8). GYTS cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
