In YOFC ADSS cable, single-mode/multimode fibres are positioned
in the loose tubes, which are made of high modulus plastic materials,
while the loose tubes strand together around non-metallic central
strength member(FRP) into a compact and circular cable core. The
loose tubes are filled with filling compound, while water-blocking
materials are distributed into interstices of the cable core. The PE inner
sheath is extruded over the cable core with aramid yarns outside.
Then, the cable is completed with a PE/AT outer sheath.
Excellent corrosion resistance, due to AT sheath
Light weight and small diameter
Large span with the largest span of over 1000m
Accurate excess fibre length and stranding pitch
to guarantee the good tensile and temperature
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 careful design of aramid yarn quantity
and stranding process can satisfy the
demand on various spans.
The life expectancy is over 30 years
