self support fiber optic cable ADSS

(ADSS) cable is a type of optical fiber cable that contains no conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors.

ADSS is an alternative to OPGW with lower installation cost. The cables are designed to be strong enough to allow lengths of up to 700 meters to be installed between support towers. ADSS cable is designed to be light weight and small in diameter to reduce the load on tower structures due to cable weight, wind, and ice. In the design of the cable, the internal glass optical fibers are supported with no strain, to maintain low optical loss throughout the life of the cable. The cable is jacketed to prevent moisture from degrading the fibers. The jacket also protects the polymer strength elements from the effect of solar ultraviolet light. Using single-mode fibers and light wavelengths of either 1310 or 1530nm, circuits up to 100 km long are possible without repeaters. A single cable can carry as many as 144 fibers.

-Small diameter, light weight, the span cam reach to 1500m, with a low additional load to the tower.

-Strong anti-pull performance, more than 90KN.

-Non-metallic structure, good insulated performance, thunder-proof.

-The equality sparn and good performance when meeting an emergency.

-Good performance of anti-gun and anti-erode

-Suitable for bad climate.

-Can work without electric stop.

-Structure characteristic Loose tube and non-metallic strengthen High flexible , can work under the environment at electric fieldsd≤25KV/m.
