The All Dielectric Self-supporting Optical Fiber Cable ADSS is loose tube stranded Fiber cable, which is 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 PE or AT (anti-tracking) outer sheath.
Features
Low attenuation, low dispersion Proper design and precise excess length control make the cable have outstanding
mechanical and environmental performance.
Non-metallic construction makes the cable resist the electromagnetic interference well.
High strength aramid yarn as strength member ensures high tensile resistance, small diameter and light weight of the cable, fitting for different weather conditions and different installation spans.
Special AT outer sheath (optional) offers good electro-erosion resisting performance.
Applications
ADSS optical fiber cable plays a significant role in the communication industry. Its usage is gradually increasing with more people choosing it in expense of other fiber cable. Some of its outstanding features have enhanced its demand throughout the market.This article analyses the key applications of the ADSS optical fiber cable. The research showed that, ADSS optical fiber cable’s demand is high particularly in areas of transmitting high-voltage power.
