Double Sheath Kevlar Yarn Reinforced ADSS Fiber Optic Cable
Description
The ADSS (All-Dielectric Self-Supporting) cable comprises loose tube stranding. Fibers are housed in high
modulus plastic tubes filled with a water-resistant compound. These tubes, along with fillers, are stranded
around a non-metallic central strength member made of FRP (Fiber Reinforced Plastic), creating a compact
circular cable core. The core is filled with a filling compound and covered by a thin polyethylene (PE) inner
sheath. Subsequently, a stranded layer of aramid yarns is applied over the inner sheath for reinforcement.
Finally, the cable is completed with either a polyethylene (PE) or anti-tracking (AT) outer sheath.
Application
1 ADSS cable design accounts for the real-time conditions of overhead power lines.
2 PE outer sheath is utilized for power lines below 110kV, while AT outer sheath is employed for 110kV and
above.
3 The specific design of aramid quantity and stranding process caters to the varying span requirements effectively.
Characteristics
1 Allows installation without requiring power shutdown.
2 Lightweight and small diameter, reducing stress from ice, wind, tower, and backprop loads.
3 Designed for a lifespan of 30 years.
4 Exhibits strong tensile strength and temperature resilience for reliable performance.
