All Dielectric Self-supporting Aerial Cable(ADSS)
1. Application
It is applied for different grades of high voltage transmission lines.
2. Advantage
☀It is applicable for the transmission wavelength 1310 mm and 1550 mm.
☀The biggest advantage of ADSS optical cable is that the cable doesn’t need the suspender by taking the advantage of the
existing pole.
☀It is applicable for the different span from 50-1000 m, it mainly uses Kevlar as the strengthening device, has good tensile
strength, bullet-proof performance and good performance in high and low temperature.
☀The cable design and experiment can comply with the IEEEP1222.
3. Section diagram
This optical cable uses 6 loose tubes (or partial gasket for packing) to wind around the FRP and become the a complete round
cable core, which is stranded of certain number of Kevlar with potentiation after being covered with PE internal sheath. Finally,
the PE external sheath will be squeezed. The loose tube is made of the materials with great temperature properties. Several single
mode or multi mode optical fiber (2-8 core) of a proper extra length and the oil jelly used for moistureproof optical fiber are put
into the tube. The slits of the cable core are fulfilled with water-blocking compound.
