Lightning poles are an effective way to protect various fixed and portable installations from lightning damage. They are different from the structure installed in the form of lightning protection masts, often referred to as “lightning rods”, because it is made of a single long pole which is raised to a height usually from 10 to 50 feet (3 to 15 meters).
The flash pole is usually not installed on the object they protect. They are designed to project well above protected areas, and are near, but do not touch protected objects. The flow of lightning is done into the basic system, not to the object.
This is the opposite of the actions of traditional “lightning rods”. They are attached to protected structures and equipment and rely on conductivity of metal parts of the structure, through grounding cable, to do lightning flow safely with respect to fire damage.
Lightning poles provide a much greater level of protection for controllers, electrical devices, and other critical equipment than traditional systems. They can also be combined with traditional structural systems to provide “spot” protection against HVAC systems, communication equipment, and assets installed by other structures.
Many lightning poles are made as a galvanized steel monopole structure. It’s very heavy, requires special transportation, and is intended only for permanent installations. These features make them expensive to be filled and installed. As a result, they are a little used outside the power substation and heavy industrial applications.
Other scale tests are represented by LBA technology PLP poles made of aluminum, lightweight, and modular for easy transportation and installation on a fixed and temporary site. This makes it relatively cheap and easy to use. These features have enabled innovative applications such as protecting irrigation water pumps and utilities, mobile satellite dishes, and mining camp structures.
Usually, alternatives from flash poles are shield cables. However, flash poles are profitable with protective cables because they are stronger, do not require several supporters, and are generally cheaper to install and maintain. Indeed, there are cases where the shield cable fails because of high lightning stroke current, places the objects below in danger, and causes the installation to be without protection!
Traditional lightning protection masts are provided with a pointed air terminal. Even though the pole with pointed tip will attract lightning more easily pushing the lightning strike to the protected area is certainly unwanted! To prevent lightning strikes, LBA PLP lightning poles are uniquely supplied with an air terminal of the UL charging dissipation listed at the top which can hinder the percentage of significant lightning stroke. This reduces the probability of Flash aside and soil voltage gradients in protected areas during local lightning events.
The protected area around the pole is called protection zone. The purpose of the design is to provide a high pole so that all the protected objects are in this zone. For example, a small building in the form of a 10-foot cube (3 meters) can be placed about 20 feet from the pole and is in the protection zone.
