All Dielectric Self-Supporting Aerial Cable 100-1000 MetersSpan AT-Sheath 12-288 Core ADSS Fiber Optic Cable
Description
All dielectric ADSS Optical cable is used for power line application, which is a structure of loose tube stranded. The fibers, 250μm , 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. 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 AT anti-tracking outer sheath.
Features
1, Can be installed without shutting off the power.
2, Excellent AT performance. The maximum inductive at the operating point of AT sheath can reach 25kV.
3, Light weight and small diameter reducing the load caused by ice and wind and the load on towers and upholder.
4, Large span lengths and the largest span is over 1000m.
5, Good performance of tensile strength and temperature.
6, The design life span is 30 years.

Application
The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed. For overhead power lines under
110kV, PE outer sheath is applied. For power lines equal to or over 110kV. AT outer sheath is applied. The dedicate design of aramid quantity and
stranding process can satisfy the demand on various spans.
