Energy-saving optical cable from Israeli manufacturer ADSS directly supplied

ADSS (All Dielectric Self-Supporting) optical cables are lightweight, metal-free aerial fiber cables designed for energy-efficient, safe, and reliable deployment along high-voltage power lines.

Overview of ADSS Optical Cable

ADSS cables are all-dielectric, meaning they contain no metallic components, which ensures electrical insulation and eliminates the risk of short circuits when installed near high-voltage lines (110 kV to 500 kV) . They are self-supporting, capable of bearing their own weight and external loads such as wind, ice, and UV exposure without additional support wires, simplifying installation and reducing infrastructure costs . This design makes them ideal for smart-grid communications, rural connectivity, and overhead fiber networks .

Structure and Design

ADSS cables typically come in two structural designs: layer stranding and central bundle tube. The layer stranding design is suitable for longer spans and higher fiber counts, while the central tube design is compact and cost-effective for short to medium spans . The internal fibers are supported with minimal strain to maintain low optical loss, and the outer jacket protects against moisture, UV radiation, and environmental wear . High-strength para-aramid fibers provide tensile strength, allowing spans of up to 1,000 meters in some installations .

Advantages

• Energy-efficient and safe: No metal reduces induced voltages and eliminates the need for grounding hardware .
• Lightweight and durable: Can be tensioned by hand for short spans and withstands harsh climates, including extreme cold and lightning-prone areas .
• Long-distance capability: Single-mode fibers allow circuits up to 60–100 km without repeaters, supporting high-bandwidth applications .
• Low maintenance: Resistant to corrosion, UV, and electrical tracking, ensuring long service life .

Installation Considerations

ADSS cables are mounted directly on power poles or transmission towers using specialized clamps, vibration dampers, and corona-proof rings . Proper hanging points are selected to minimize electrical stress and avoid collisions with conductors or ground wires, especially for high-voltage lines . Accessories such as tension clamps, suspension clamps, and armor rods are used to secure the cable and maintain stability over long spans .

Applications

ADSS cables are widely used in:

• Overhead high-voltage transmission systems below 35 kV, and in some cases up to 110 kV .
• FTTX projects, including FTTH (fiber to the home) and FTTA (fiber to the antenna) deployments .
• Smart-grid and utility communications, where reliability and electrical safety are critical .
• Harsh environments, including coastal, lightning-prone, and cold-climate regions .

Conclusion

Energy-saving ADSS optical cables from an Israeli manufacturer offer a reliable, safe, and efficient solution for aerial fiber deployment. Their metal-free, self-supporting design reduces installation complexity, enhances durability, and ensures compatibility with high-voltage power lines, making them suitable for modern utility and telecom networks. For direct supply, interested buyers should contact the manufacturer to confirm availability, technical specifications, and shipping options.
