One primary disadvantage of steel electrical pylons is their susceptibility to corrosion.
Steel Pylon Disadvantage: Corrosion
According to references, steel is subject to the corrosive effects of chemicals and pollution. This means that over time, exposure to environmental factors can degrade the steel structure of the pylon.
- Causes of Corrosion:
- Chemicals: Industrial emissions, de-icing salts near roads, or chemical spills can react with the steel.
- Pollution: Air pollution containing corrosive substances can accelerate rust formation.
- Environment: Coastal areas with saltwater spray or areas with high humidity and temperature fluctuations can also contribute to corrosion.
Impact of Corrosion
Corrosion weakens the steel, which can compromise the structural integrity of the pylon. This requires regular inspection, maintenance, and potentially costly repairs or replacement to ensure the safety and reliability of the power grid.
While early manufacturing processes did produce types of steel resistant to corrosion, ongoing exposure to harsh environments means that corrosion remains a significant factor to manage for steel pylons throughout their lifespan.
