All-dielectric self-supporting optical cables are made entirely of dielectric materials and contain the necessary support systems. They can be directly hung on non-metallic optical cables on power towers.
PE sheath: ordinary polyethylene sheath. Used for power lines below 110KV.
AT sheath: Anti-tracking sheath. Used for power lines above 110KV. Required support systems and non-metallic fiber optic cables that can be hung directly from power towers.
(1) Specifically designed for power systems, it is a fully insulated self-supporting overhead optical cable, and the structure does not contain any metal materials;
(2) Fully insulated structure with high voltage resistance index, which is conducive to live installation and construction of overhead power lines without affecting the operation of the lines;
(3) Use anti-fiber materials with high tensile strength, which can withstand strong tensile forces, meet the requirements of large spans of overhead power lines, and can prevent birds from pecking and people from shooting;
(4) The thermal expansion coefficient of ADSS optical cable is small. When the temperature changes greatly, the curvature of the optical cable line changes very little, and it is light in weight and is less affected by ice and wind loads.
The national standards for ordinary optical cables clearly stipulate the mechanical strength that optical cables used in different ways (such as aerial, pipeline, direct burial, etc.) should have. ADSS optical cable is a self-supporting overhead optical cable, so it not only has to withstand the long-term effects of its own gravity, but also the baptism of the natural environment. If the mechanical performance design of the ADSS optical cable is unreasonable and does not adapt to the local climate, the optical cable will have safety hazards and its lifespan will be reduced. Therefore, each ADSS optical cable project must be designed according to the natural environment and span of the optical cable wiring. The installation span of ADSS optical cable can reach 1800 meters per section, and it has high voltage resistance, good resistance to electrical corrosion, and lightning protection. It can be laid on transmission line poles and towers with a voltage level of 500kV. It has strong resistance to gunfire. Generally, it can be shot with a sand gun at a distance of 10 meters without causing any damage to the cable. It has strong low temperature resistance and strong environmental adaptability. Optical cables are laid independently without relying on transmission lines, making construction and maintenance easy and without the need for power outages. Optical cables are also relatively cheap. It also has strong low-temperature resistance and environmental adaptability. Optical cables are laid independently without relying on transmission lines. Construction and maintenance are convenient, no power outages are required, and optical cable prices are relatively cheap.
