GYTC8A Self-Supporting Aerial Fiber Optic Cable with Aluminum Armor

The structure of the optical cable is to insert single-mode or multi-mode optical fibers into a loose tube made of high modulus plastic filled with waterproof compound. The center of the cable core is a metal reinforcing component. For some optical cables with certain core numbers, the structure of the optical cable is to insert single-mode or multi-mode optical fibers into a loose tube made of high modulus plastic filled with waterproof compound. A polyethylene cushion layer is extruded and wrapped around the metal central reinforcing part. Loose tubes (and filling ropes) are twisted around the central reinforcing part to form a compact and round cable core. The gaps inside the cable core are filled with water-blocking compound. An aluminum-polyethylene bonded sheath is extruded and wrapped outside, and steel strand hangers are added to form the cable.

Laying methods: self-supporting, overhead, etc.

Application scope: Suitable for long-distance communication and inter-office communication, etc.

Execution standard: YD/T 1155-2011 "8" shaped self-supporting optical cable for communication.

• The reasonable design and precise control of the excess length of the optical fiber in the loose tube and the cabling method endow the optical cable with excellent mechanical and environmental performance;
• The outside of the reinforcing parts and the inside of the cable core are filled with water-blocking cable paste to ensure the moisture-proof and water-blocking effect of the optical cable.
• The optical cable has excellent flexibility and resistance to bending.
• The longitudinal wrapping of the cable core with aluminum strips makes the moisture-proof effect of the optical cable more excellent.
• Steel strands have extremely high tensile strength and are convenient for self-supporting overhead laying.
