ADSS Cable Long Span Aerial Self Supporting for FTTH Network
Hone ADSS cable is used as a communication medium in electrical utilities. It’s installed along existing overhead transmission lines and shares the same support structure as electrical cable.
Description
ADSS cable is short for all-dielectric self-supporting fibre optic cable. With light weight itself and armid yarn protection, it is strong enough to support itself between poles or tower without using conductive mental elements. It’s an alternative to OPGW with lower installtion costs.
All 250um fibres are protected by water-resistant tube filling compound filled high modulus plastic loose tubes. And all tubes (and fillers) are stranded around a mom-metallic central strength member RFP (fibre reinforced plastic) into a compact and circular cable core. Then there are a layer of stranded aramid yarn between cable core and outside PE ( or AT )sheath. For ADSS cable need extra protection of 2 sheath, inner PE sheath will be applied between cable core and aramid yarn.
Application
Aerial and self supporting for backbone network
Distribution for FTTH network
Features
- ADSS cable is lightweight and strong enough for Self-supporting
- Installation without shutting off the power
- All-dielectric self-supporting with light weight
- Small diameter
- Reduce the load caused by ice and wind
- Large span can meet up over 1000m for ADSS cable
- Good tensile and temperature performance
