Depending on the height of the building, the need for lightning protection may vary. Here's a breakdown of both cases:
Cases in which lightning protection is not required:
For general buildings, if the height does not exceed 50 meters, special lightning protection treatment is usually not required. This is because these buildings are relatively safe in a lightning environment. In addition, for some of the lower buildings, even if they are located in a thunderstorm-prone area, the surrounding buildings may provide them with some protection due to their low height.
Situations where lightning protection is required:
Lightning protection is essential for buildings with a height of more than 50 meters, especially those located in lightning-prone areas or with no other buildings around to provide protection. These buildings can be targeted by lightning, so steps need to be taken to reduce the risk of lightning injury to buildings and people.
In order to ensure the safety of a building, a series of lightning protection measures are usually required. These include installing lightning rods, lightning belts or lightning nets on the roof of buildings to direct lightning currents into the ground. In addition, it is also necessary to ensure that the electrical wiring and equipment inside the building are protected by lightning protectors to prevent lightning currents from entering the room and causing damage to people and equipment.
In summary, the need for lightning protection depends on the specific height of the building, the environment in which it is located, and the sensitivity of the equipment inside. For buildings with a height of more than 50 meters or buildings located in lightning-prone areas, lightning protection is very necessary. For other buildings, it can be decided whether lightning protection treatment is required according to the actual situation.
