Overhead Double Jacket Multi Cores Multimode ADSS Fibra Optic Cable
Description
The ADSS (All-Dielectric Self-Supporting) optical fiber cable is
specifically designed to utilize existing high
voltage transmission towers for installation. Its benefits include
cost-effectiveness, ease of construction,
heightened safety, and simplified maintenance.
The ADSS cable, widely employed globally, serves as a popular
choice for power communication due to its
versatility and reliability.
Application
* 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.
Characteristics
* Exceptionally low attenuation and dispersion due to precise
design and excess length control, ensuring
remarkable mechanical and environmental performance.
* Non-metallic construction facilitates cable laying without
interrupting power systems.
* Utilization of high-strength aramid yarn as a strength member
provides superior tensile resistance, enabling
a small diameter and lightweight cable suitable for various weather
conditions and installation spans.
* Optional special AT (anti-tracking) outer sheath delivers excellent
electro-erosion resistance capabilities.
