What is modern lightning protection?

To understand what modern lightning protection is, we have to understand a little bit about classic lightning protection. Here, I just list a little basic, everyone passing by understands immediately.

Classic lightning protection is basically using sharp iron and steel sections at one end, pointing the pointing head upwards to direct lightning strikes, about 0.8m long to 1.2m. These iron bars will be seen on the roof or school roof, then weld these iron bars together and lead to the ground or weld straight into the column steel, foundation steel works. This measure is passive, when lightning strikes, lightning follows the steel bar to the ground.

This lightning protection method is less effective because the lightning current steel is not as good as copper, not to mention over time the steel is rusted, rotting, damaged. When lightning strikes, it cannot escape to the ground, causing great damage to houses and buildings, not to mention endangering human life.

In order to overcome the above disadvantages and safe for human life in the house and works, the modern lightning protection system was born.

The characteristic of the modern lightning protection system is that it has a lightning needle that actively emits a pioneering ray to draw charge towards it, minimizing the lightning flow, lightning flow cable is a copper cable so the lightning flow is very fast, does not affect the house and construction.

Why fight lightning?

Lightning strikes are a natural phenomenon, it has huge consequences for homes and buildings and is extremely dangerous for human life. Lightning strikes cause fires, forest fires, deadly because the lightning current is very large, and the lightning current temperature creates extremely high. Therefore, we need to install a lightning protection system.

How much does it cost to install a modern lightning protection system?

Installing a modern lightning protection system costs very little, but it offers many benefits. It brings safety to homes and buildings, safety to human life. The cost of installing a housing project including supplies, equipment and labor ranges from 15 to 20 million, which is too cheap for the value it brings. As for works and projects, depending on the capacity and scale of the works, there is an appropriate design and estimate.

What are the benefits of installing a modern lightning protection system for housing and construction?

1. Ensure the safety of the house and the building, because if lightning hits the house and the building is very vulnerable to severe damage: cracks, broken walls, columns; fire and explosion; complete damage to electrical appliances in the house: lights, power cables, televisions, refrigerators,….
2. Restrictions that pose a danger to human life in homes and buildings when struck by lightning

Notes when installing lightning protection systems for houses and works

1. The installation of lightning protection system must be in accordance with the principle, otherwise it will not be effective, on the contrary, it will cause serious consequences.
2. Do not install or construct lightning escape cables, lightning transmission cables of lightning protection systems going inside the building, besides electrically sensitive devices: televisions, network equipment, sensors,… Why, because lightning is so large, creates a magnetic field that acts on these electronic devices.
3. It is best to ride a lightning lead cable, escape the lightning of the lightning protection system outside the building
4. When erecting lightning rods, it is necessary to pay attention when drilling into the floor to install the base of the pillar and the cables dodging the needle firmly when the wind is stormy because it will be soaked with rainwater and in the construction, the installation personnel should pay attention to this problem so that the lightning protection system brings the highest efficiency.
5. Copper lightning escape cable, section 50mm2 or 70mm2 so very valuable, installed outside the house so it is easy to be cut, note to use protective measures such as threading cables in pipes, sections under the feet carefully, I thread into the protective pipe steel section.
6. Note that the lightning escape cable needs to be welded to the ground pile of the landing site, if the connection is not guaranteed, on the contrary, it is not effective but receives very heavy consequences because the needle actively collects lightning but cannot escape to the ground, so the work is sufficient.
7. After installation, it is necessary to measure the resumentation of the resuming, less than 10 Ohm is satisfactory, if more, drill more wells, connect more geodesical piles or use chemicals to reduce the resuming of the resuming, the lower the lightning escape. After each year, it is necessary to measure again, if not achieved, renovate to make the lightning protection system operate safely, otherwise the consequences will be extremely serious.
8. We need to hire an inspection unit on the measurement of the ground resistance of the lightning protection system, so that they issue quality papers, serving the needs of bringing works and projects into business.
