Non-metallic Strength Member Non-armored Cable(GYFTA)
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. After an Aluminum Polyethylene Laminate (APL) moisture barrier is applied around the cable core, the cable is completed with a PE sheath.
DESCRITION OF PRODUCT
Characteristics
- Good mechanical and temperature performance.
- Special tube filling compound ensure a critical protection of fiber.
- Specially designed compact structure is good at preventing loose tubes from shrinking.
- Excellent crush resistance.
- 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 901-2001 as well as IEC 60794-1.
