Lightning rods, also known as air terminals, are devices widely utilized to safeguard buildings and tall trees from the devastating effects of lightning strikes. These devices are typically installed at the highest point of the protected object, with a wire connecting them to a grounding network that meets specific requirements.

When a thundercloud discharges close to the ground, it alters the surrounding electric field. At the top of the lightning rod, a localized area of heightened electric field concentration is created. This concentration influences the direction of the lightning's pilot discharge, guiding it to the lightning rod. The lightning current is then safely channeled into the earth through the grounding conductor and grounding device, effectively protecting the object from direct lightning strikes.

The lightning rod's design features a three-pole configuration, making it detachable and easy to install. This convenience ensures that users do not have to worry about lightning safety, as the lightning rod can be easily deployed to safeguard various structures, including towers, oil tankers, and high-rise buildings.

Measuring 37 centimeters in height, the lightning rod boasts a straightforward installation process, with four screw holes provided at the base to secure it in place. Crafted from brass with a surface plating, this lightning rod is both durable and aesthetically pleasing, making it a reliable choice for lightning protection.

In summary, the lightning rod is a versatile and essential device that effectively shields buildings and tall trees from the destructive power of lightning strikes. Its three-pole design, detachability, and easy installation process make it a convenient and practical solution for ensuring lightning safety in a wide range of applications.
