4; Stranded Loose Tube Non-metallic Strength Member Non-armored Cable
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 the cable core is filled with the filling compound to protect it from water ingress, the cable is completed with a PE sheath.
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; Crush resistance and flexibility;
5; The following measures are taken to ensure the cable watertight:
A; Single Fiber Reinforced Plastic as the central strength member;
B; Loose tube filling compound;
C; 100% cable core filling;
