Double Sheath Kevlar Yarn Reinforced ADSS Fiber Optic Cable
Description
ADSS (All-Dielectric Self-Supporting) cables utilize 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 shielding them from moisture. These tubes, along with fillers, are
stranded around a central strength member made of non-metallic FRP (Fiber Reinforced Plastic), creating
a compact and circular cable core.
To enhance protection, the core is filled with a compound and enclosed in a thin polyethylene (PE) inner
sheath. Additional reinforcement is provided by a layer of stranded aramid yarn applied over the inner sheath.
Finally, the cable is completed with an outer sheath, which can be either polyethylene (PE) for standard
applications or anti-tracking (AT) for environments with high electrical stress.
This robust construction ensures that ADSS cables are highly durable, moisture-resistant, and capable of
withstanding various environmental conditions. Suitable for both aerial and underground installations, these
cables offer reliable performance
across a wide range of applications.
Application
1. The design of ADSS optical cables meticulously incorporates the real-time conditions of overhead power
lines, ensuring optimal performance and durability in such environments.
2. PE outer sheaths are utilized for power lines below 110kV, while AT outer sheaths are employed for power
lines operating at 110kV and above to provide enhanced protection.
3. Specific design elements such as the quantity of aramid yarns and the stranding process are precisely
tailored to effectively meet diverse span requirements. This ensures the reliable operation of the optical
cable across various installation scenarios.
Characteristics
1. Allows for installation without the need for a power shutdown, minimizing service disruptions during
deployment.
2. Its lightweight and compact diameter reduce strain from ice, wind, towers, and backpropagation loads,
thereby enhancing the cable's durability and overall performance.
3. Designed for a 30-year lifespan, ensuring long-term reliability and cost-effectiveness in infrastructure
projects.
4. Demonstrates strong tensile strength and temperature resilience, ensuring consistent performance across
diverse environmental conditions.
