Optical Fibre Cable
Flame-Retardant Double-Armoured Cable
GYTZY53
Steel-wire central member · flame retardant · double sheath
Steel-wire central strength member with flame-retardant sheathing and a double-sheath, corrugated-steel-tape armoured build. The choice where both fire performance and heavy mechanical protection are specified.
Key features
- Good mechanical and thermal performance
- Steel wire as the central strength member
- Hydrolysis resistant loose tube
- Tube filling compound ensures critical protection of fiber
- Stranded compact structure eliminating contraction of tubes
- LSZH jackets ensuring good flame-retardant performance
- 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 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. Then the core is filled with water blocking compound and covered with PE inner jacket. After the steel tape is longitudinally armored over the inner jacket, the cable is completed with a LSZH outer jacket.
