Outdoor All Dielectric Self-supporting Aerial Cable

SOPTO ADSS 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 filling compound. The tubes (and fillers) are stranded around 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 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 or 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 25KV
• light weight and small diameter reducing 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
• accurate control on Aramid application greatly improving the strength of cables
• accurate fiber excess length and stranding pitch to ensure the good performance of tensile strength and temperature
• the design life span is over 30 years.

Application

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 delicate design of Aramid quantity and stranding process can satisfy the demand on various spans… [Details]
