GYTS/GYFTS Cable
Stranded Loose Tube Light-armored Cable
The 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 metallic or FRP wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a 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.
Features
Good mechanical and temperature performance
High strength looes tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Specially designed compact structure is good at preventing loose tubes from shrinking
Crush resistance and flexibility
PE sheath protects cable from ultraviolet radiation
The following measures are taken to ensure the cable watertight:
– Steel/FRP wire used as the central strength member
– Loose tube filling compound
– 100% cable core filling
– PSP enhancing moisture-proof
Standards
GYTS/GYFTS cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
