Special AT(Anti-tracking) Outer Sheath Strong Electric Erosion ADSS
Fiber Optic Cable
The ADSS optical cable adopts a loose tube stranded structure. The
250µm optical fiber is sheathed in a loose tube made of high
modulus material,
and the loose tube is filled with waterproof compound. The loose
tube (and the filling rope) is twisted around the non-metallic
central reinforcement core (FRP) to form a compact cable core, and
the gaps in the cable core are filled with water blocking grease.
The cable core is extruded into a polyethylene (PE) inner sheath,
then stranded to strengthen the aramid fiber, and finally it's
completed by the polyethylene (PE)
The design of ADSS optical cable fully considers the actual
situation of power lines and is suitable for different levels of
high-voltage power transmission lines. For 10kV and 35kV power
lines, polyethylene (PE) sheath can be used; for 110kV and 220kV
power lines, the cable hanging point must be determined by
calculating the electric field intensity distribution and the
electric tracking (AT) outer sheath must be used. At the same time,
the amount of aramid fiber and the perfect stranding process are
carefully designed to meet the application requirements of
different spans.
Features
1. Low attenuation, low dispersion Proper design and precise excess
length control make the cable have outstanding
2. mechanical and environmental performance. 3. Non-metallic
construction makes the cable resist the electromagnetic
interference well. 4. High strength aramid yarn as strength member
ensures high tensile resistance, small diameter and light weight of
the cable, fitting for different weather conditions and different
installation spans. 5. Special AT(anti-tracking) outer sheath
(optional) offers good electro-erosion resisting performance.
