Please refer to the technical specification.Active lightning protection – the active lightning rod is raised at the highest point of the building. This system attracts the forming lightning and directs all the current away from other elements of the building. The activity occurs only during a lightning discharge. When choosing an active lightning rod, pay attention to whether the lightning receiver has electronics (can withstand up to 115kA, but may fail if the discharge exceeds the limits) or no electronics (can withstand any strength and number of lightning discharges). Used for the protection of industrial complexes, buildings, residential houses, estates, warehouses, and stadiums.

Passive lightning protection – metal elements installed on the roof (traditional "Franklin" lightning rod). During a lightning strike, the current flows through this metal system into the ground. Typically, galvanized steel wire is used, which is laid along the entire roof length and dropped to the ground. Occasionally, copper wire is used, but due to cost differences, users usually opt for steel, which is cheaper. Around the building, a galvanized steel grounding strip is laid underground.

A lightning rod protects buildings and people from the effects of lightning, but does not protect equipment. Therefore, it is essential to install surge protection.
