All Dielectric ADSS Fiber Optic Cable Self Supporting For High Voltage Transmission System
All Dielectric ADSS Fiber Optic Cable Self Supporting For High Voltage Transmission System
Description:
ADSS optical cable can be erected without powering off. AT sheath gives it excellent electric tracking resistance. This type of optical cable has light weight and small cable diametwe, which reducing the influence of wind and ice, on the tower and support load, largest span can be 200 meters. With excellent tensile properties and temperature characteristics, life expectancy is greater than 30 years.
Advantages:
Good aramid yarn have excellent tensile performance
Fast delivery, 200km ADSS cable regular production time about 10 days.
Glass yarn is available instead of aramid yarn, to prevent mouse bite.
Characteristics:
- PE outer sheath for overhead power lines such as 10kv, 35kv.
- AT outer sheath for power lines such as 110kv, 220kv.
- The deliberate design of uses of aramid yarn can satisfy the demands on the conditions, such as climate, various spans and sag etc.
- Good performance of tensile strength and temperature.
- Small diameter and lighter of the cable reducing the loss caused by ice and wind on the towers and supporting structures.
Standards:
- IEC60794-1
- DL/T788
- YD/T980
Product Features:
- Low optical fiber transmission loss and low dispersion.
- Endow cables with excellent mechanical properties and environmental performance due to reasonable design and precise control over excess length of optical fibers in loose tube and cabling mode.
- Keep structure compact, and protect the cable from stress under hostile environment by use of SZ stranded structure.
- Fill waterproof cable gel outside the reinforcer and inside cores, ensuring its moisture proof and water proof effect.
- Provide more excellent moisture proof effect as well as bullet proof function as the cores are wrapped longitudinally by steel tape.
- The steel strand as the self supporting member meets the higher tensile strength.
