[Case Study] 132kV Grid Modernization in Coastal Brazil: High-Strength Galvanized Steel Poles Replacing Corroded Wood Poles

[Case Study] 132kV Grid Modernization in Coastal Brazil: High-Strength Galvanized Steel Poles Replacing Corroded Wood Poles

2024-05-30

[Case Study] 132kV Grid Modernization in Coastal Brazil: High-Strength Galvanized Steel Poles Replacing Corroded Wood Poles

 

1.Project Overview

  • Location: Northeastern Coastal Brazil
  • Challenge: Located in a C5-M (High Saline) environment, the original wood poles suffered from termite infestation and high-humidity decay, with a lifespan under 15 years. Increasing industrial loads also exceeded the flexural capacity of the aging infrastructure

2. Technical Solution

  • High-Strength Steel: Utilizing ASTM A572 Grade 65 with $450text{ MPa}$ yield strength. This reduced pole weight by 30% compared to concrete, simplifying installation in marshy coastal terrains.
  • Corrosion Resistance: Hot-dip galvanizing per ASTM A123 with a coating thickness of $86text{ mu m}$ - $100text{ mu m}$, supplemented by bituminous coating on the embedment section for underground protection.

3. Performance & Evidence

  • Stability: Pull-out tests confirmed tip deflection stayed within $pm 1%$ under max design tension, meeting ASCE 48 safety standards.
  • Longevity: Simulation analysis predicts a maintenance-free service life exceeding 50 years in coastal Brazilian conditions.

4. Conclusion

 

The project lead noted: "Switching to steel poles resolved the corrosion pain points while the slip-joint design shortened on-site assembly time by 20%."
