AdSS self-supporting optical cable models

ADSS (All-Dielectric Self-Supporting) cables are non-metallic fiber optic cables designed to support their own weight, available in multiple models optimized for span length, fiber count, and environmental conditions.

Overview of ADSS Cables

ADSS cables are lightweight, fully dielectric optical cables that can be installed along power distribution or transmission lines without the need for messenger wires or metal support elements . They are suitable for medium- and high-voltage environments, with typical applications ranging from 12 kV to 500 kV, depending on the model and sheath design . The cables are designed to withstand wind, ice, and temperature extremes, with operating temperatures from -40°C to +60°C and storage up to +70°C .

Common ADSS Cable Models

1. AFL-ADSS®
   • Fiber counts: Varies; Flex-Span models support a broad combination of fiber counts.
   • Design: Single jacket, aramid yarn reinforcement for tensile strength and elongation.
   • Applications: Distribution and transmission networks, including live-line installations.
   • Features: Simplified installation with compatible AFL attachment hardware .
2. Corning SOLO ADSS
   • Fiber counts: 12–144 fibers.
   • Design: SZ-stranded loose tube, track-resistant polyethylene (TRPE) jacket.
   • Applications: Medium-span aerial installations.
   • Features: Easy one-step installation, mid-span access, and fiber isolation from environmental stress .
3. Rosen Cable ADSS
   • Voltage range: 12 kV–25 kV.
   • Design: Loose-tube, gel-filled, double-sheathed with aramid or fiberglass reinforcement.
   • Environmental resistance: UV-resistant HDPE jacket, water-blocking elements, and ballistic protection.
   • Standards: ISO 9001, ISO 14001, IEC 60793, ITU-T G.652, IEC 60794 .
4. Other Common Models
   • ADSS-12J, ADSS-24, ADSS-48F: Selected based on span length, voltage class, and environmental conditions. Longer spans require higher tensile strength and sag control, while high-voltage lines may require AT-sheath insulation .

Key Selection Criteria

• Span length: Determines tensile strength and sag performance; longer spans need stronger cables.
• Voltage level: High-voltage lines require insulating sheaths to prevent electrical tracking.
• Environmental conditions: Wind, ice, temperature, and UV exposure influence material choice and jacket type.
• Fiber count and network capacity: Single-mode fibers with 1310 or 1550 nm wavelengths can support circuits up to 100 km without repeaters .

Summary

ADSS cables provide a cost-effective, self-supporting solution for overhead fiber optic networks. Model selection depends on fiber count, span length, voltage, and environmental factors, with options from manufacturers like AFL, Corning, and Rosen Cable offering flexibility for distribution, medium-span, and long-distance transmission applications .
