What are the primary advantages and disadvantages of underground cables compared to overhead lines?
2025-08-11Answer: The choice between underground cables and overhead lines is a key consideration in power line projects, with each having distinct pros and cons.
underground Cables:
-
Advantages: Higher reliability in severe weather (wind, ice storms), better aesthetics with no visual clutter, and reduced public safety risks from accidental contact.
-
Disadvantages: Significantly higher installation cost (often 4-14 times more expensive), more difficult and time-consuming to locate and repair faults, and lower current-carrying capacity (ampacity) due to heat dissipation challenges.
-
Advantages: Lower initial cost, faster and easier installation and maintenance, and simple fault location.
-
Disadvantages: Vulnerable to damage from weather and external factors (e.g., trees), can be an eyesore, and require a larger right-of-way easement for safety.
