The choice between overhead lines and underground cables depends on various factors, each with its own advantages and disadvantages.

overhead lines:

• Advantages: Generally a lower-cost option for power transmission, easier to install and repair, and more effective at dissipating heat.

• Disadvantages: More susceptible to weather-related outages (e.g., wind, lightning, ice), have a larger visual impact, and require regular vegetation management.

underground Cables:

• Advantages: Less susceptible to weather, have a lower visual impact, and are considered safer in terms of public interaction.

• Disadvantages: Significantly more expensive to install, more difficult and time-consuming to locate and repair faults, and require specialized trenching and laying equipment.
