ADSS Cable Structure and Design
ADSS cable adopts a loose tube stranded construction for reliable fiber protection. The optical fibers, 250μm, are
housed in loose tubes made from high-modulus plastic, providing
excellent mechanical strength and durability.
Each tube is filled with a water-blocking gel, preventing moisture ingress and protecting fibers from long-term
water damage. The tubes and fillers are stranded around a central FRP (Fiber Reinforced Plastic) strength member, creating a compact and round cable core that is completely
non-metallic, safe for use near power lines.
The cable core is filled with filling compound for additional water blocking, then covered with a thin PE (polyethylene) inner sheath to provide a smooth and stable structure. A stranded layer of aramid yarns is applied over the inner sheath, offering outstanding tensile
strength and resistance to mechanical stress. Finally, the cable is
completed with either a PE outer sheath for general outdoor use or an AT (anti-tracking) outer sheath for installation in high-voltage environments (≥110 kV).
Additional Benefits
Dielectric Design: No metallic elements, eliminating grounding requirements.
Long Service Life: Excellent UV resistance and weatherproof performance.
Lightweight and Easy to Install: Self-supporting design reduces installation cost and time.
Customizable: Available in various fiber counts (up to 288 cores) and sheath
materials to suit different span lengths and project needs.

Application:
* The actual status of overhead power lines is taken into full
consideration when ADSS cable is being designed.
* For overhead power lines under 110kV, PE outer sheath is applied.
* For power lines equal to or over 110kV, AT outer sheath is
applied.
