Double Jacket Kevlar Yarn Strengthen Self Supporting Cable ADSS Fiber

Optic Cable

Description

The ADSS cable employs a loose tube structure housing fibers within high modulus plastic. These tubes

contain a water-resistant filling compound and are arranged around a Fiber Reinforced Plastic (FRP), se-

rving as a central non-metallic strength member. This assembly forms a compact circular core. Following

the filling of the cable core, it receives a thin PE inner sheath. Next, a stranded layer of aramid yarns is a-

pplied over this sheath for added strength, and finally, the cable is finished with a PE or AT outer sheath.

Application

1 ADSS cable designs account for the specifics of existing overhead power lines.

2 PE outer sheaths are used for lines under 110kV; AT sheaths for 110kV and higher.

3 Tailored aramid quantity and stranding techniques meet various spans' requirements.

Characteristics

• Installable without power shutdown, ensuring uninterrupted service.

• Lightweight and small diameter, minimizing strain from ice, wind, and tower/backprop loads.

• Designed for a lifespan of 30 years, offering prolonged reliability.

• Exhibits excellent tensile strength and temperature performance.
