Non - Metal Strengthening  Aluminum Armored  FO GYFTA 2~288 Core  (LX2025)

Configuration & Physical characters

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 Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. Waterproof filling compound filled into whole cable core, an Aluminum Polyethylene Laminate (APL) moisture barrier applied around the cable core and finally PE sheath completed over APL as outer protection.

Product Features & Application

Characteristics:

1. Good mechanical and temperature performance

2. High strength loose 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. The following measures are taken to ensure the cable watertight:

....Single Fiber Reinforced Plastic as the central strength member

....Loose tube filling compound

....100% cable core filling

....APL moisture barrier

Standards:

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