All-dielectric self-supporting optical cable

Product Description: 

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 non-metallic reinforcing component (FRP). For some optical cables with certain core numbers, A polyethylene cushion layer is extruded from the outside of the non-metallic central reinforcing piece. Loose tubes (and filling ropes) are twisted around the central reinforcing piece to form a compact and round cable core. The cable core is longitudinally wrapped with water hose, and a polyethylene inner sheath is extruded. The outer side is twisted with aramid yarn for reinforcement and then an outer sheath or an AT resistant outer sheath is extruded to form the cable.

Installation method: Self-supporting overhead use on power poles and towers.

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

Execution standards: YD/T 980-2002 All-dielectric self-supporting optical cable, D/LT 788-2016 All-dielectric self-supporting optical cable, etc.

Product features:

① 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;

② Light in weight and with a small cable diameter, it reduces the impact of ice and wind forces as well as the load on the tower and supports.

③ For power circuits above 110KV, AT sheaths can be adopted, which have excellent resistance to electrical tracking.

④ It has excellent tensile strength and temperature performance;

⑤ It can be set up directly without power interruption.

⑥ Large span, with the maximum span exceeding 1000M; The expected lifespan design of the optical cable can be greater than 30 years.
