ADSS cable is loose tube stranded. Fibers, 250m, are positioned into a loose tube made of high modulus plastics. The tubes are lied with a water-resistant filling compound. The tubes (and Ilers) are stranded around a FRP (Fiber Reinforced Plastic) as a non-metallic central strength member into a compact and circular cable core. After the cable core is lied with filling compound, it is covered with thin PE (polyethylene) inner sheath. After stranded layer of aramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or A T(anti-tracking) outer sheath.
All-dielectric self-supporting
(Fiber Optic Cable) 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.
Fiber Optic Cable is an alternative to OPGW with lower installation cost. The cables are designed to be strong enough to allow lengths of up to 700 metres to be installed between support towers. Fiber Optic Cable 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 1530 nanometres, circuits up to 100 km long are possible without repeaters. A single cable can carry as many as 144 fibers.
