A lightning arrester is a protective device used in electrical power systems to safeguard the insulation and conductors from the destructive effects of lightning strikes. It works by diverting the high voltage from a lightning surge safely to the ground, preventing damage to the system. The typical lightning arrester consists of two main components: a high-voltage terminal, which connects to the power system, and a ground terminal, which directs the surge energy into the ground. By doing so, it helps to maintain the integrity and reliability of the electrical infrastructure.

The busbar is also frequently used to power the (horizontal and vertical) backbones of buildings used for the commercial-service sectors, thus observing the time required for the installation and providing a final solution with remarkable technical advantages. BEL busbars are available in three segmented ranges (Low Power, Medium Power, High Power, Lighting & Trolley BBT) are able to meet all installation requirements from 25Ato 6300A according to IP-55 & IP-56
