Stranded Loose Tube Non-metallic Strength Member Cable – GYFTA

Stranded Loose Tube Non-metallic Strength Member Cable – GYFTA
Stranded Loose Tube Non-metallic Strength Member Cable – GYFTA-1

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 Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. Tubes and fillers are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, the cable is completed with a PE sheath.
