China factory price g652d 16 core double sheath adss fiber optic cable
ADSS cable is the short form for All-dielectric Self-supporting Optical Cable. The actual status of overhead power lines is taken into full consideration when ADSS cable is being designed. For overhead power lines under 110kV, PE outer sheath is applied. FOR power lines equal to or over 110kV, AT outer sheath is applied. The dedicate design of aramid quantity and stranding process can satisfy the demand on various spans.
ADSS Cable Structure:
1. Optical fiber cable
2. Fiber jelly
3. PBT loose tube
4. Filling compound
5. Central strength member FRP
6. Filling rope
7. PE inner sheath
8. Aramid yarn
9. Outer sheath
ADSS Cable laying mode: Self supporting overhead
ADSS Cable operation temperature: -40~ +65℃
ADSS Cable Features:
(1) Lightweight and small diameter reduces the impact of ice and wind, and their impact on tower and supporter.
(2) Large span length: Max span>1000 meters, and the optical cable can be installed without electrical outage.
(3) Project design added (sag-tension, field intensity calculation, hanging point selection, hardware fittings configuration).
