ОКЛТ-Т
General information
A-D(ZN)2Y(SR)T2Y / A-D(BN)2Y(SR)T2Y (ОКЛТ-Т) type fiber optic cable armored with laminated corrugated steel tape armor, double-sheathed, with (eight-stranded) suspension rope 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). Optical fibers are freely placed inside the tube and interstice is filled with a hydrophobic gel. In addition to aramid yarns or fiber glass yarns, polyethylene inner jacket is imposed on the central tube. Internally jacketed cable core is sheathed with laminated corrugated steel tape armor, and the bearing member is sheathed with a high-density polyethylene outer jacket.
