Definition of Lightning Protection Steel Tower

A lightning steel tower is a tower device used to protect buildings from lightning disasters. It is usually composed of tower bodies, platforms, ladders, antenna support, lightning rods, flashers, feeder brackets and grounding conductors. The material of the lightning protection steel tower is generally Q235 steel. It has been hot-dip galvanized and has good corrosion resistance and a service life of more than 30 years. The height of the lightning protection steel tower is usually between 10 meters and 40 meters, and the tower height required by special design can reach 120 meters.

The lightning protection principle of lightning protection steel towers is to introduce lightning into the ground through metal conductors, thereby protecting buildings, their internal equipment and personnel from lightning damage. The design and installation of lightning protection steel towers must comply with the national standards “Building Lightning Protection Design Code”, “Heighth Structure Design Code”, “Mast Tower Construction and Acceptance Regulations”, etc. Lightning protection steel towers are not only used in high-risk areas such as oil refineries, chemical plants, coal mines, etc., but are also widely used in communication base stations, radio and television towers, microwave communication towers, etc.

The grounding system of the lightning protection steel tower is an important part of it, ensuring that lightning current can be safely introduced to the ground. The grounding system includes a grounding body, a grounding wire and a grounding resistor, and the grounding resistance should be less than 5 ohms. In addition, during the installation of the lightning protection steel tower, attention should be paid to factors such as wind, rain and snow weather and visibility to ensure construction safety.

In short, lightning protection steel tower is an efficient and reliable lightning protection device, which is widely used in various high-risk areas and important buildings, effectively reducing losses caused by lightning disasters.
