Stranded Loose Tube Light Armored Cable – GYTA

GYTA

Central Strength Member is Steel Wire

GYTA

Cable Structure:

The 250um bare 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 the 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 over 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.

Note:

Other fiber types are available upon request.

Features:

  1. Crush resistance and flexibility
  2. Good mechanical and temperature performance
  3. PE sheath protects the cable from ultraviolet radiation
  4. High strength loose tube that is hydrolysis resistant
  5. Special tube filling compounds ensure a critical protection of fiber
  6. A specially designed compact structure is good at preventing loose tubes from shrinking
  7. The following measures are taken to ensure the cable is watertight:

Steel wire used as the central strength member

Loose tube filling compound

100% cable core filling

APL moisture barrier
