ОКТ-Т
General information
A-DT2Y (ОКТ-Т) type fiber optic cable with a central tube on which a single-layer (eight-stranded) suspension rope is put for suspension on power line pylons
STRUCTURAL DESIGN OF CABLE
The bearing member is placed in parallel to the twisted conductor. The bearing member can consist of a steel rope or a dielectric-based strength member (fiberglass rod). The cable core consists of the central tube. Optical fibers are freely placed inside the tube and interstice is filled with a hydrophobic gel. The high-dense outer jacket is imposed on the cable core (tube) and parallel bearing
- Steel rope (T)/ steel wire (Ts)
- Glass rod (Td)
- PBT tube
- Optical fiber
- Hydrophobic gel
- Outer protective jacket
