All-Dielectric Self-Supporting (ADSS) cables have become a cornerstone of modern fiber optic networks, particularly in power transmission environments. Their unique design—free of metallic components and capable of self-supporting over long spans—makes them ideal for deployment on existing power lines, towers, or harsh terrains. Globally, certain ADSS cable models stand out due to their adaptability, performance, and compliance with international standards. Below, we explore the most sought-after ADSS cable models in overseas markets and the reasons behind their popularity.
1. ADSS-12B1 to ADSS-144B1 Series: Core Count Flexibility
ADSS cables with fiber counts ranging from 12B1 (12 cores) to 144B1 (144 cores) are widely adopted in Europe, North America, and Asia-Pacific regions. The "B1" designation refers to standard single-mode fibers (ITU-T G.652.D), which dominate long-distance and high-bandwidth applications.
Key Features:
Scalability: Utilities and telecom operators favor these models for their flexibility in backbone networks and last-mile connectivity.
Durability: Designed with aramid yarn strength members and dual-layer sheathing (PE or AT/UV-resistant), they withstand extreme temperatures (-40°C to +70°C) and UV exposure.
Compliance: Meet IEC 60794 and IEEE 1222 standards, ensuring global interoperability.
Popular Applications:
Power grid communication systems (smart grids).
Long-span rural broadband projects.
2. ADSS-LS (Long Span) Series: High Tensile Strength
In regions prone to severe weather—such as coastal areas or mountainous zones—the ADSS-LS series is preferred for its enhanced mechanical performance. These cables support spans exceeding 1,000 meters and tolerate tensions up to 30 kN, making them ideal for challenging installations.
Key Features:
Robust Design: Reinforced with high-modulus aramid fibers and trapezoidal cross-section loose tubes to prevent buckling.
Anti-Galloping: LS models often incorporate vibration dampers to mitigate wind-induced oscillations.
Regional Demand:
High adoption in North America (e.g., Canadian power grids) and Northern Europe (e.g., Scandinavian countries).
3. ADSS-AT (Anti-Tracking) Series: For Polluted Environments
In industrial or coastal regions with high pollution (salt, dust, or chemical deposits), the ADSS-AT series excels. Its anti-tracking sheath prevents electrical arcing and surface degradation, a critical feature for installations near high-voltage lines.
Key Features:
Silicone-Coated Sheath: Provides hydrophobicity and resists corona discharge.
Corrosion Resistance: Ideal for Middle Eastern deserts and Southeast Asian coastal zones.
Standards:
Complies with CIGRE Technical Brochure 640 for pollution-resistant cables.
4. ADSS-FR (Fire Retardant) Series: Urban and Tunnel Deployments
Urban infrastructure projects prioritize fire safety, driving demand for ADSS-FR models. These cables feature low-smoke, zero-halogen (LSZH) sheaths to minimize toxic emissions during fires.
Key Applications:
Metro systems (e.g., London Underground, Singapore MRT).
Power tunnels in cities like Tokyo and New York.
5. Customized ADSS Solutions: Region-Specific Variants
Manufacturers such as Prysmian Group (Italy), Fujikura (Japan), and Corning (USA) offer tailored ADSS models for niche markets:
Cold-Climate Variants: Extra-flexible sheaths for Arctic regions (e.g., Alaska, Russia).
High-Temperature Variants: For desert environments (e.g., Saudi Arabia, UAE).
Why These Models Dominate Overseas Markets?
Adaptability: From dense urban hubs to remote power grids, these models address diverse climatic and structural demands.
Compliance: Alignment with IEC, IEEE, and regional standards (e.g., ANSI in the U.S., CENELEC in Europe) ensures regulatory acceptance.
Cost Efficiency: Reduced installation costs (no separate messenger wire) and minimal maintenance.
Supplier Reputation: Trust in global brands like Nexans and OFS Fitel drives preference for their certified ADSS portfolios.
Conclusion
The global popularity of ADSS cable models hinges on their technical versatility and alignment with regional challenges. As 5G rollout and smart grid modernization accelerate, demand for high-fiber-count, pollution-resistant, and long-span ADSS cables is poised to grow further. Utilities and telecom providers continue to prioritize these models to future-proof their infrastructure against evolving connectivity needs.
