Single Sheath Outdoor Aerial Fiber Optic All-Dielectric Self-Supporting Cable
ADSS
Description
The cable features high modulus plastic tubes housing the fibers, filled with a water-resistant compound.
Surrounding this, a layer of Kevlar provides additional protection. A water-blocking material is applied between
the Kevlar yarn and the loose tube, ensuring a compact and waterproof structure. To finalize its design, the
cable is enveloped in a durable polyethylene (PE) sheath, safeguarding it against external elements.
Application
This specification outlines the general prerequisites for single jacket ADSS (All-Dielectric Self-Supporting) cables
suitable for aerial or duct installations.
Characteristics
* Exceptional mechanical and temperature performance.
* Hydrolysis-resistant, high-strength loose tube.
* Specialized tube filling compound for crucial fiber protection.
* Crush resistance combined with flexibility.
* Tensile strength supported by dual parallel steel wires.
* Compact size, lightweight build, and easy installation for user convenience.
