Introduction
The
ADSS cable is loosely wound and the 250μm fiber is placed in a loose tube made
of high modulus material. The loose tube is filled with waterproof compound.
The loose tube (and the filling rope) is twisted around a non-metallic center
reinforcing core (FRP) into a compact core with a gap between the core and a
water-blocking paste. The outer core of the cable is extruded into a
polyethylene (PE) inner sheath, and then the reinforced aramid is twisted, and
finally a polyethylene (PE) outer sheath or an electrical tracking (AT) outer
sheath is extruded.
Features
Can
be erected continuously.
With
AT sheath, it has excellent resistance to electric tracking.
Light
weight and small cable diameter reduce the impact of ice, wind and load on
towers and supports.
Large
span with a maximum span of more than 1000m.
Excellent
tensile and temperature properties.
Life
expectancy can be up to 30 years.
