The fibers are positioned in loose tubes that are made of high-modulus plastic and filled with tube gel. The tubes (and fillers) are stranded around a metallic central strength member to form a cable core. The core is filled with water-blocking compound and then armored with laminated aluminum tape(APL). Finally, a LSZH outer 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 metallic strength member to form the cable core. Then the cable core is filled with water-blocking compound and covered with a PE inner jacket. After the corrugated steel tape (CST) is longitudinally armored over the inner jacket, the cable is completed with a PE outer jacket.
 

Fibers are positioned in a central tube made of high-modulus plastic and filled with tube gel. The tube is armored with aramid yarns and water blocking yarns. Finally a LSZH jacket is extruded.

The fibers are positioned in loose tubes that are made of high-modulus plastic and filled with tube gel. The tubes (and fillers) are stranded around a non-metallic central strength member(FRP) to form a cable core. The core is filled with water blocking compound and armored with corrugated steel tape( CST). Then a LSZH outer sheath is extruded
 

● Good mechanical and thermal performance
● FRP central strength member
● Hydrolysis resistant loose tube
● Tube filling compound ensures critical protection of fiber
● Specially designed stranded compact structure eliminating contraction of tubes
● LSZH sheath ensuring good flame-retardant performance
● Crush resistance and flexibility
● Water-blocking measures :
- Loose tube gel-filled
- 100% cable filling compound
- APL moisture barrier
- Corrugated steel tape (CST) enhancing moisture-proof
