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 non-metallic central strength member into a compact and circular cable core. After the cable core is filled with compound. It is covered with thin PE(Polyethylence) inner sheath. After stranded layer of aramid yarns are applied over the 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-tranking) outer sheath.
Features:
1.Cable be installed without shutting off the power;
2.Exnt AT performance.Maximum inductive at the operating point of AT sheath can reach 25KV;
3.Light weight and small diameter reducing the load caused by ice,wind,load on towers and backprops;
4.Large span lengths(Largest span is over 1000m)
5.Good performance of tensile strength and temperature;
6.Design life span is 30 years.
Standards:
ADSS cable complies with Standard IEE P 1222&IEC60794-1
Applications:
The actual status of overhead power taken into full consideration when ADSS cable is being designed. For overhead power er 110KV,PE outer sheath is applied. For power al 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.
