The application of ionization devices in lightning rod needle-shaped electrodes.
The lightning rod consists of three parts: an ionization device, connecting wires, and a grounding device. It is designed based on the principle of discharge at the tips of metal needle-like electrodes. Under the influence of the electric field of a thundercloud, when the field strength at the tip reaches a certain value, the surrounding air becomes ionized and, under the influence of the electric field force, moves away, while other air molecules are subsequently ionized to take their place. This process continues, resulting in an ionic current flowing from the metal tip to the surrounding area. As the potential increases, the ionic current increases exponentially. When lightning occurs above the lightning rod and the protected equipment, the lightning rod and the nearby ground induce charges that are opposite in polarity to those of the thundercloud.

A simple explanation of a self-supporting guyed tower.
In the design of large tower structures, the use of flexible inclined rods is generally more economical and reasonable. The guyed tower is a special case of flexible inclined rod design where the rods are fixed to the ground. It is widely used in various voltage lines in China, demonstrating significant economic benefits. However, to reduce the cost of power transmission lines, it is necessary to research and explore the design of new flexible inclined rod towers, aiming to maintain the steel consumption of guyed towers.
