Double Sheath Kevlar Yarn Reinforced ADSS Fiber Optic Cable

Description

ADSS (All-Dielectric Self-Supporting) cables feature a loose tube stranded construction to ensure optimal

performance and durability. The optical fibers are securely housed in high modulus plastic tubes filled with

a water-resistant compound, effectively protecting them from moisture. These tubes, along with fillers, are

stranded around a central strength member made of non-metallic FRP (Fiber Reinforced Plastic), forming

a compact and circular cable core.

For enhanced protection, the core is filled with a compound and encased in a thin polyethylene (PE) inner

sheath. A layer of stranded aramid yarn is then applied over the inner sheath for additional reinforcement.

Finally, the cable is finished with an outer sheath, which can be either polyethylene (PE) for standard

applications or anti-tracking (AT) for high electrical stress environments.

This robust construction ensures that ADSS cables are highly durable, moisture-resistant, and capable of

withstanding various environmental conditions. Ideal for both aerial and underground installations, these

cables provide reliable performance across a wide range of applications.

Application

1. The design of ADSS optical cables fully considers the real-time conditions of overhead power lines,

ensuring optimal performance and durability in such environments.

2. Power lines below 110kV use PE outer sheath, and power lines 110kV and above use AT outer sheath

to provide enhanced protection.

3. Specific design elements such as the number of aramid yarns and the twisting process are tailored to

effectively meet different span requirements. This ensures the reliable operation of the optical cable in

different installation scenarios.

Characteristics

1. Facilitates installation without requiring a power shutdown, minimizing service disruptions during deployment.

2. Its lightweight and compact diameter reduce strain from ice, wind, towers, and backpropagation loads,

enhancing the cable's durability and overall performance.

3. Engineered for a 30-year lifespan, ensuring long-term reliability and cost-effectiveness in infrastructure

projects.

4. Exhibits robust tensile strength and temperature resilience, guaranteeing consistent performance across

diverse environmental conditions.
