ADSS optical cable adopts a loose-tube stranded structure. 250 µm optical fibers are inserted into loose tubes made of high-modulus material, and the loose tubes are filled with a waterproof compound. The loose tubes (and fillers) are stranded around a non-metallic central strength member (FRP) to form a compact cable core, and the gaps in the cable core are filled with water-blocking grease. A polyethylene (PE) inner sheath is extruded over the cable core, then aramid yarn is stranded for reinforcement, and finally a polyethylene (PE) outer sheath or a tracking-resistant (AT) outer sheath is extruded.
• Can be installed without power interruption
• AT sheath provides superior tracking resistance
• Light weight and small cable diameter, reducing the effects of ice and wind and the load on towers and supports
• Long span, with a maximum span of more than 1,000 meters
• Excellent tensile performance and temperature characteristics
• Expected service life of more than 30 years
