1, many rural houses will directly install lightning rods to prevent being struck by lightning in thunderstorm season, and then lay lines along the wall. This method is also feasible.
2. Pay attention to the use of wooden poles when laying lightning rods, but the height of wooden poles should be at a certain distance, and the selection of wires is also required. Generally speaking, you can choose 6 square meters or 10 square meters of wires.
3. If it is a metal roof, you can directly connect the ground wire from the roof, and then lay down the down lead along the roof to connect with the ground wire.
Second, the lightning protection and grounding methods of high-rise buildings
There are many high-rise buildings in the city, so it is necessary to install lightning protection grounding bodies in place during construction, and welding is generally used.
1, when selecting grounding body, round steel or angle steel can be selected, and the requirements must be met. If round steel is selected, its diameter must be not less than 10 mm, and if angle steel is selected, its thickness must not be less than 4 mm.
2, can be installed in the reinforced column grounding wire, and then leads to two, one of which can be used as a down lead.
3, in the specific construction operation, but also in accordance with the design drawings for laying, must be in strict accordance with the specification, do a good job of lightning protection and grounding.
Third, do not do the harm of lightning protection and grounding.
When we install some electrical appliances, such as air conditioners or electric water heaters, we will do a good job of lightning protection and grounding. If a building is not grounded, the harm is still great.
Thunderstorm season is easy to be struck by lightning, which may cause switch tripping and short circuit of wires. In severe cases, it will cause equipment damage and even lead to life safety.
The above points are about how to construct lightning protection grounding and the harm of not doing lightning protection grounding, hoping to attract attention.
