All Dielectric Self-supporting Aerial Cable – ADSS

All Dielectric Self-supporting Aerial Cable - ADSS

Cable Structure:
ADSS cable is loose tube stranded. The 250um bare fibers 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 stranded layer of armaid yarns are applied over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath.

Remark:
ADSS cables with other spans are also available.
Specifications in the table are on condition that there is no height difference and the installation sag is 1%.

Features:

  • The design life span is 30 years.
  • Can be installed without shutting off the power
  • Good performance of tensile strength and temperature
  • Large span lengths and the largest span is over 1,000m
  • 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 backprops

Standard:

  • IEC 60794-1
  • IEEE 1222-2004

Application:

  • Self-supporting aerial
  • 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.
