ADSS All Dielectric Self-supporting Aerial Fiber Optic Cable
Product description:
ADSS cable is loose tube stranded. 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 the stranded layer of aramid yarns is applied over the inner sheath as a strength member, the cable is completed with PE or AT (anti-tracking) outer sheath.
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.
Product characteristics:
Can be installed without shutting off the power;
Lightweight and small diameter reduce the load caused by ice and wind and the load on towers and back props;
Large span lengths and the largest span is over 1000m;
good performance of tensile strength and temperature.
