What are the main advantages and disadvantages of overhead lines versus underground cables?

2025-08-13

Choosing between overhead and underground power systems involves a careful balance of benefits and drawbacks.

  • overhead lines:

    • Advantages: Generally less expensive to install and repair. They are easier to inspect and maintain, and faults are simpler to locate and fix.

    • Disadvantages: More susceptible to damage from severe weather like wind, ice, and lightning. They also have a larger visual impact on the landscape.

  • underground Cables:

    • Advantages: Provide greater reliability as they are protected from weather and external damage. They are also aesthetically pleasing and safer for the public as they are not exposed.

    • Disadvantages: Installation costs are significantly higher due to excavation and specialized materials. Faults are difficult and time-consuming to locate and repair.
