ADSS (All Dielectric Self-supporting Aerial Cable) is loose tube stranded. Fibres are positioned into a loose tube made of high modulus plastics. The tubes are filled with a water-resistant around FRP(Fibre 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 a thin polyethylene (PE) inner sheath. After two layers of Aramid yarns are applied in two directions over the inner sheath as strength member, the cable is completed with PE outer sheath.
