ОКЛмТ-Т

General information

A-D(ZN)(SR)T2Y / A-D(BN)(SR)T2Y (ОКЛмТ-T) type fiber optic cable with a central tube armored with laminated corrugated steel tape, single-layer-coated, with (eight-stranded) suspension rope for suspension on power line pylons

Cable Construction Design

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. The cable core is sheathed with aramid yarns or fiberglass yarns and laminated corrugated steel tape armor, the bearing member is sheathed with a high-density polyethylene outer jacket.
