The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member （FRP) to form the cable core. Then the core is filled with water blocking yarns and longitudinally wrapped with water blocking tapes. The cable is completed with a PE outer jacket.

● Good mechanical and thermal performance
● Steel wire as the central strength member
● Hydrolysis resistant loose tube
● Tube filling compound ensures critical protection of fiber
● Specially designed stranded structure eliminating contraction of tubes
● Rugged, durable PE jacket protects against UV radiation, fungus etc.
● Crush resistance and flexibility
● Water-blocking measures :
- Loose tube gel-filled
- 100% cable filling compound
- Corrugated steel tape(CST) enhancing moisture-proof

The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member （FRP) to form the cable core. Then the cable core is filled with the cable jelly to protect it from water penetration. Finally a PE jacket is extruded.

The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member （FRP) to form the cable core. Then an aluminum tape (APL) is armored longitudinally around the cable core, which is filled with water blocking compound. Finally a PE jacket is extruded.
