ADSS Single Jacket Fiber Optic Cable Span 100m

ADSS (All Dielectric Self-Supporting) Aerial Overhead Outdoor Fiber Optic Cable Single Jacket SPAN 100m

Description:

ADSS fiber optic cable is a specialized all-dielectric, self-supporting optical transmission medium designed for long-distance, high-bandwidth communication—especially in power system networks (e.g., overhead power lines). Unlike traditional fiber cables that require external support (e.g., messenger wires), ADSS relies on its own dielectric (non-conductive) structure to bear mechanical loads (weight, wind, ice), making it ideal for environments where electrical conductivity is a hazard (e.g., near high-voltage power lines).

ADSS is defined by two essential attributes:

• All-Dielectric: No metallic components (e.g., steel wires, copper shielding) are used. This eliminates electrical conduction, avoiding induced currents from nearby high-voltage power lines (a critical safety feature for power grid applications).

• Self-Supporting: Its structural design provides sufficient tensile strength and rigidity to be installed independently (e.g., strung between power towers) without relying on additional support cables.

It integrates optical fiber cores (for data transmission) with dielectric strength members and protective layers, balancing communication performance, mechanical durability, and electrical safety.

Internal Structure:

ADSS cables follow a layered design, with each component serving a specific function. The structure varies slightly by manufacturer but typically includes the following layers:

Advantages:

• Electrical Safety: All-dielectric construction eliminates metallic components, so it does not conduct electricity. This prevents induced voltages/currents from high-voltage power lines (avoids equipment damage and electric shock risks).

  
  

• Self-Supporting Convenience: No need for a separate messenger wire or support structure. Reduces installation time, labor, and costs—especially when retrofitting onto existing power towers.

• Excellent Mechanical Performance:

• High tensile strength ( aramid yarn/ FRP strength members) to withstand overhead loads (e.g., ice accumulation, strong winds).

• Good flexibility for easy handling during installation.

  
  

• Weather & Environmental Resistance:

• UV-stabilized outer sheath resists degradation from sunlight.

• Water-blocking layers and moisture-resistant materials prevent corrosion or signal loss due to humidity.

• Wide operating temperature range (-40°C to +70°C), suitable for extreme climates (deserts, high-altitude areas, cold regions).

  
  

• High Bandwidth & Low Loss: Uses single-mode fibers (typical for long distances) with low attenuation (~0.21 dB/km at 1550 nm), enabling high-speed data transmission (10 Gbps, 100 Gbps) over tens or hundreds of kilometers.

Applications:

ADSS is most widely used in scenarios where electrical safety, self-support, and outdoor durability are critical. Key applications include:

1. Power System Communication (Primary Use Case)

• Power Grid Monitoring & Control: Transmits real-time data (e.g., voltage, current, equipment status) between substations, control centers, and power generation facilities. Enables smart grid operations (e.g., load balancing, fault detection).

• Overhead Power Line Retrofitting: Installed alongside high-voltage (HV) or extra-high-voltage (EHV) power lines (110 kV to 1000 kV) on existing towers. Eliminates the need to build new support structures, reducing costs.

  
  

2. Telecommunication Networks

• Rural/Remote Area Connectivity: Strung between utility poles or towers to provide high-speed internet/voice services in areas where laying underground cables is impractical (e.g., mountainous regions, farmland).

• Long-Distance Backhaul: Used as a backhaul link between cell towers or telecom hubs, leveraging its low signal loss for long spans (e.g., connecting cities or rural hubs to core networks).

  
  

3. Industrial & Special Environments

• Renewable Energy Plants: Connects solar farms, wind parks, or hydroelectric facilities to the main grid, transmitting power generation data and control signals.

• Railway & Transportation: Installed along railway lines to support train communication systems (e.g., signaling, passenger Wi-Fi) or along highways for intelligent transportation systems (ITS).

• Mining & Oil/Gas: Used in non-explosive, outdoor areas (e.g., surface mining sites) to transmit operational data, as its dielectric structure avoids spark risks.
