Overhead Electric Power ADSS Fiber Optic No Armoured Cable Track-resistant Outer Sheath High voltage HDPE 110KV

       ADSS cable, Loose tube construction, tubes jelly filled, tubes with filler rods lay up around non-metallic FRP (Fiber-glass Reinforced Plastic) central strength member, water-blocking material, aramid yarns reinforced and HDPE outer sheath.

ADSS cable is up to 144 optical fibres in jelly-filled loose tubes, laid up around a central non-metallic strength member. The cable is water blocked, aramid yarn reinforced and polyethylene sheathed. Surface printing for the cable includes sequential length marking at one-metre intervals. Mainly installed at existing 220kV or lower voltage power lines . Two Jacket and stranded loose tube design.

Two important materials: 1.  It is Track-resistant HDPE; 2.  Imported aramid.

 

1 Cable design

1. 48 SM-fibers

2. G652 D operating wavelength at 1260~1625nm.

3. FRP as central strength member.

4. Loose buffer tubes SZ-stranded.

5. The buffered tube filled with filling compound while the stranded core covered with water block material

6. Aramid yarns as peripheral strength member

7. Track-resistant HDPE(PE outer sheath is applied for the application in which cable is installed at the place where the spatial potential ≤12KV)

8. Suitable as: Aerial installation (Span:150m)

2 Reference Standard
