What are the primary advantages of underground electric transmission?
2025-08-16underground electric transmission is an increasingly popular alternative to traditional overhead lines, especially in urban areas and locations prone to severe weather. The main benefits include:
-
Enhanced Reliability: underground cables are protected from external factors such as lightning strikes, high winds, ice storms, and falling trees. This dramatically reduces the risk of power outages and increases grid resilience.
-
Aesthetics and Space: Burying power lines eliminates the need for large, unsightly towers and poles, preserving the landscape and allowing for more efficient use of land in densely populated areas.
-
Improved Safety: The risk of accidental contact with live conductors is eliminated, significantly reducing the danger of electrocution for the public and wildlife.
-
Reduced Maintenance: Once installed, underground cables require less routine maintenance compared to overhead lines, which need regular inspections for corrosion, tree trimming, and storm damage.
