All-dielectric Self-supporting ADSS fiber optic cable has a different structure from overhead conductors. Its tensile strength is borne by aramid yarn. The elastic modulus of aramid yarn is smaller than that of steel-more than half, and the coefficient of thermal expansion is a fraction of that of steel, which determines that the sag of the ADSS fiber optic cable is more sensitive to external load changes.
This type is able to obtain longer fiber lengths. Although the diameter and weight are relatively big, ADSS cables with this structure are better to be deployed for large span applications. The structure of ADSS fiber cable can be in a stranded structure design, the inner optical fibers and water-blocking grease are added into the fiber loose tube, and different loose tubes are wound around the central reinforcement (usually FRP). The rest parts are basically similar to the central tube structure.

ADSS Fiber optic cable of aramid yarn is a important part for fiber optical cable for tensile resistance. The ADSS fiber cable have a wide temperature range(-40℃ ~+80℃) and small cable diameter, it is more convenient to reduces ice and wind loads and maintains stable transmission. The inner structure use a water-blocking layer for better waterproofing. They provide tensile strength to the finished cable assembly. It is very convenient line installation and maintenance.
As a kind of self-supporting aerial fiber optic cable, ADSS (All-dielectric Self-supporting) cable is designed for aerial installation and deployment, which is suitable for various outdoor applications. ADSS fiber optic cables have become the first choice of special optical cables for power system networking.

All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements.
UnitekFiber can supply ADSS fiber optic cable with 100-800 meter pole span.
Dielectric means it has non-conducting properties of a non-metallic, insulating material that resists the passage of electric current.
ADSS cables should be placed in Aerial and duct, but can not be direct-buried.
