Underground cables can be more expensive to install and maintain compared to overhead lines due to the complexity of excavation and the need for specialized equipment. They are also more challenging to access for repairs, which can lead to longer outage times in case of faults. Additionally, underground cables are susceptible to water infiltration and soil movement, potentially compromising their integrity.
