Double Sheath Aramid Yarn Reinforcing ADSS Self Supporting Cable
Description
The ADSS cable employs a loose tube stranded design, housing fibers within high modulus plastic tubes
filled with a water-resistant compound. These tubes, along with fillers, are wrapped around a non-metallic
central strength member (FRP) to form a tight circular cable core, which is then filled with compound for
added protection. A thin PE inner sheath is applied over the core, followed by a layer of aramid yarns for
strength. Finally, the cable is finished with either a PE or AT outer sheath for additional protection and in-
sulation.
Application
1 ADSS cable design adapts to overhead power line specifics.
2 PE outer sheath for lines below 110kV; AT sheath for 110kV+ lines.
3 Tailored aramid and stranding suit diverse span requirements.
Characteristics
1 Non-disruptive installation without power shutdowns.
2 Light and small size to alleviate ice, wind, tower, and backprop loads.
3 30-year design life expectancy.
4 Excellent tensile strength and temperature performance.
