Cable Information

Uninet ADSS cable is loose tube standard. Fibers are positioned into a loose tube of high modulus plastics. The tubes filled with a water-resistant filling compound. The tubes (and fillers) are stranded around Fiber Reinforced Plastic (FRP) 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 yarn applied in two directions over the inner sheath as strength member, the cable is completed with PE or AT (anti-tracking) outer sheath.

Cable Characteristics
  • The Cable can be installed without shutting off the power.

  • Excellent AT performance. The maximum inductive at the operative of AT sheath can reach 25kV.

  • Light weight 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.

  • Accurate control on Aramid application greatly improves the tensile strength of cables.

  • Accurate fiber excess length and stranding lay length ensure good performance of tensile strength and temperature.

  • The design life span is over 30 years.
