GYTA Multimode Fiber Optic Cable, outdoor single mode fiber optic cable
GYTA Multimode Fiber Optic Cable, Outdoor Single Mode Fiber Optic Cable
Description
- ADSS cable is loose tube stranded. Fiber, 250m, is positioned into a loose tube made of high-modulus plastic. The tubes are lied with a water-resistant lling compound. The tubes(and llers) are stranded around an FRP(Fiber Reinforced Plastic) as a non-metallic central strength member into a compact and circular cable core. After the cable core is filled with filling compound, it is covered with thin PE(polyethylene) inner sheath. After a stranded layer of aramid yarns is applied over the inner sheath as a strength member, the cable is completed with PE or AT(anti-tracking) outer sheath.
Features
- Can be installed without shutting off the power.
- Excellent AT performance. The maximum inductive at the operating point of AT sheath can reach 25kv.
- Light weight and small diameter reducing the load caused by ice and wind adn the load on towers and backprops.
- Large span lengths and the largest span ia over 1000m.
- Good performance of tensile strength and temperature.
- The desing life span is over 30 years.
Application
- Aerial for power cable transmission line, self - supporting.
