All-Dielectric Self-Supporting Optic Fiber Cable (ADSS) is loose tube stranded. Fibers 250 µ m are positioned into a loose tube made of high modulus plastics. The tubes are filled with a water-resistant filling compound. The tubes (and fillers) 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 filled with filling compound is covered with thin PE(polyethylene) inner sheath. After stranded layer of pyramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or AT(anti-tracking) outer sheath.
Application of ADSS: Self-supporting overhead
Characteristics of ADSS:
1.Can be continuously electric erection
2.Using the AT sheath, electrical erosion resisting superior performance
3.Light weight, small cable diameter, reducing the ice, wind and the effect to the tower, supports the load
4.Large span, the largest span more than 1000 meters
5.Aramid armoured process accurately control greatly improves the tensile capacity of cable
6.Fiber excess length and precise control cable stranding pitch to ensure cable
7.With tensile property and excellent temperature characteristics
8.The life expectancy of more than 30 years
ADSS is complied with standard IEEE 1222-2004 as well a IEC 6079-1
ADSS is using polyethylene for power lines 10kV and 35kV (PE) coat; for power lines 110kV and 220kV by calculating the electric field distribution must be defined cable hanging point and the use of electrical erosion resistant (AT) outer sheath. At the same time, the careful design of aramid quantity and stranding process to meet the requirements of application of different span.
