The heavy damage is due to the fact that almost all the power lines and telecommunication cables are suspended in the air, which can hardly withstand a big storm. Strong winds are strong enough to knock down concrete poles, so the power lines and cables are useless. Not to mention, when the storm comes, the power grid and telecommunication cables are also affected by falling trees, flying roofs, and collapsing houses, so damage is inevitable.
Undergrounding of power grids and telecommunication cables has been implemented in some localities, but not much, some places are gradually doing it line by line. Based on the actual damage caused by Typhoon Yagi, perhaps localities should be determined to invest in undergrounding this system.
Undergrounding power grids and telecommunication cables requires a huge amount of capital, not to mention depending on the synchronization of urban infrastructure. However, even though it is costly, it must be done for the long-term benefit and sustainability of the entire system, ensuring stability in the supply of electricity and telecommunication services to the people, even in the event of natural disasters.
Power lines and telecommunication cables are buried underground, which will minimize damage caused by storms and rains. Businesses do not have to spend a lot of money to repair and restore lines. This is a benefit that can be calculated in money. Even if a storm comes, the system will not be paralyzed, power outages will be limited, and there will be enough electricity for daily life and production. Telecom businesses will still provide normal services, which is the second benefit.
Underground power lines minimize the risk of electrical short circuits and explosions, ensuring people's safety.
This benefit alone cannot be fully calculated, because fire safety is related to people's property and lives.Underground power grids and telecommunication cables not only increase safety during storms, but also at all times in daily life.In fact, people live in places where power lines are tangled, because the risk of fire and explosion is very high.
Another huge benefit is that burying power grids and telecommunication cables underground is clearing away “airborne trash”, a common type of trash in urban areas in Vietnam. Imagine, in Hanoi, Ho Chi Minh City and many other cities, if this type of trash were cleared away, the streets would be cleaner, brighter and much more beautiful.
