Description

ADSS cable is loose tube stranded . Fibers, 250um , 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 circular cable core . After the cable is filled with compound . It is covered with thin PE (polyethylene) inner sheath .After stranded layer of aramid yarns are applied over the inner sheath as strength member . The cable is completed with PE and AT (anti-tracking ) outer sheath.

 

Characteristics

Can be installed without shutting off the power

Excellent AT performance , The maximum inductive at the operating point of AT sheath can reach 25 kv

Light weight and small diameter reducing the load caused by ice and the wind and the load on tower backprops .

Large span lengths and the largest span is over 1000m

Good performance of tensile strength and temperature

The design life span is over 30 years

 

Applications

The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed . For overhead power lines under 110 kv , PE outer sheath is applied . For power lines equal to or over 110 kv , AT outer sheath is applied .The dedicate design of aramid quantity are stranding process can satisfy the demand of various spans .
