Single Jacket ADSS (All-Dielectric Self-Supporting) Cable is a high-performance fiber optic cable designed for aerial installations, particularly in environments with moderate mechanical stress. Its lightweight, all-dielectric construction makes it ideal for deployment near power lines without the need for grounding. Below is a detailed description of its features and applications:

Core Structure:

• Optical Fibers: The cable contains 250μm fibers housed in loose tubes made of high-modulus materials, ensuring flexibility and protection against mechanical stress.
• Water-Resistant Filling: The loose tubes are filled with a water-resistant compound to prevent moisture ingress and protect the fibers over long-term use.
• Central Strength Member: A non-metallic Fiber Reinforced Plastic (FRP) core acts as the central strength member, providing stability and tensile strength while ensuring dielectric properties.

Core Protection:

• Water-Blocking Components: The gaps within the compact, circular cable core are filled with water-blocking yarn and wrapped with a water-blocking tape to ensure moisture resistance in outdoor environments.

Strengthening Elements:

• Aramid Yarn Reinforcement: Layers of aramid yarn are applied around the cable core, offering excellent tensile strength and resistance to mechanical stresses, including wind and ice loading.

Outer Sheath:

• PE or AT Sheath: The cable is covered with a durable polyethylene (PE) or anti-tracking (AT) sheath. The AT sheath is specifically designed for installations near high-voltage power lines to resist electrical discharges and tracking.

Key Features:

1. All-Dielectric Construction: Ensures no electrical conductivity, making the cable safe and easy to install near live power lines.
2. Lightweight and Self-Supporting: Reduces the load on poles and supporting structures, simplifying installation.
3. Moisture Resistance: Water-blocking elements and tight sealing protect against environmental moisture.
4. UV and Weather Resistance: The outer sheath offers excellent protection against UV radiation, extreme temperatures, and harsh weather conditions.
5. High Tensile Strength: Aramid yarn reinforcement allows for long-span installations with minimal risk of mechanical failure.

Applications:

• Aerial Fiber Networks: Suitable for medium-span aerial installations in rural and urban environments.
• Power Line Corridor Deployment: Designed for installations near medium- to high-voltage power lines.
• Telecommunication and Utility Networks: Ideal for reliable data transmission in overhead networks.

Technical Specifications:

• Fiber Count: Typically available in configurations from 2 to 144 fibers.
• Span Length: Supports moderate spans, typically up to 800 meters, depending on fiber count and environmental conditions.
• Operating Temperature: -40°C to +70°C.

Conclusion:

The Single Jacket ADSS Cable is a reliable and efficient solution for aerial fiber optic networks. Its lightweight, all-dielectric design, combined with water-blocking features and a durable outer sheath, ensures consistent performance in demanding outdoor environments. Ideal for power line corridors and medium-span installations, this cable delivers long-lasting performance with minimal maintenance.
