What are the Causes of faults in underground cables?

Faults in underground cables can be caused by various factors, including physical damage from excavation activities, rodent infestations, or natural events like landslides and flooding. Environmental factors such as temperature fluctuations and soil movement can also lead to insulation degradation. Additionally, electrical stresses, aging infrastructure, and poor installation practices may contribute to cable faults over time. Regular maintenance and monitoring are essential to mitigate these risks.
