OKL ADSS fiber optic cable suspension self-supporting aerial cable
OKL ADSS fiber optic cable suspension aerial cable
Application:
Cable is designed for application and operation on overhead utility and power lines under the impact of strong winds and ice-loading or their combinations. When electric field potential exceeds 12kV an antitracking polyethylene in sheath should be used.
Cable design:
1. Optical fibers acc. ITU-T G.652 D / G.657A1.
2. Loose Tubes – PBT (polybutylene terephthalate).
3. Core filling – thixotropic gel.
4. Fastening winding of yarns and tapes.
5. Central strength member (fiber reinforced plastic).
6. Fillers (if applicable).
7. Inner sheath – polyethylene (HDPE).
8. Peripheral strength members - aramid yarns.
9. Outer sheath – polyethylene (HDPE).
Design versions:
1. Waterblocking tapes and yarns (“dry” core)
2. Multimode Fibers ITU-T G.651.1; IEC 60793-2-10.
3. Outer sheath: antitracking polyethylene.
