Double Layer Aerial ADSS Cable: The fibers are positioned in a loose tube made of PBT. The tubes are filled with a water-resistant filling compound. A fibre reinforce plastic locates in the center of core as a non-metallic strength member.
The tube(and the fillers) are stranded around the strength member into a compact and circular core.
The cable core is covered with a PE inner sheath. After the aramid yarns covered over the inner sheath, the cable is completed with a PE or AT outer sheath.
