ADSS structure and application design description
ADSS cable is designed as a beam stranding structure, mainly consisting of 6 stranding and 8 stranding.
*FRP, glass reinforced fiber, as center tension element and anti-folding element.
*PBT, polybutylene terephthalate, as beam tube material, inserted fiber with appropriate residual length and filled with water blocking paste.
* Aramid yarn, as a tensile strength component, the number of aramid yarn is designed according to the strength requirements of ADSS, and the ADSS has extremely high tensile strength and stress-strain characteristics by adjusting the balance of aramid yarn winding.
* Jacket, inner jacket adopts black PE, outer jacket is divided into ordinary PE and electric mark PE, corresponding to the space potential ≤12kV and >12kV working environment.
ADSS optical cable is mainly used for increasing optical channel of existing 110kV and below voltage grade lines and constructing optical network quickly. Therefore, it is necessary to find suitable "space" to install ADSS cable on the original tower. The application design of ADSS includes two aspects:
* Gear - tension - sag design
* Calculate the spatial potential distribution of the tower to determine the position of ADSS hanging point to avoid electrical corrosion
The fault
Typical structural parameters of ADSS:
Suitable for typical specifications of C=5mm,V=30m/s weather conditions
