A Type I lightning arrester is designed to provide the highest level of protection as the first line of defense against overvoltage events caused by direct lightning strikes or high-energy surges.
For example:
33 kV lightning arrester: Installed at the entry point of a substation or high-voltage line, it can effectively intercept and discharge the enormous energy generated by direct lightning strikes, preventing damage to main equipment such as transformers, switchgear, and busbars.
10 kV lightning arrester: Commonly used in medium-voltage distribution networks, it absorbs and diverts the majority of lightning energy, reducing the stress on downstream equipment and ensuring stable operation of the power grid.
11 kV lightning arrester: Plays a critical role in preventing powerful lightning surges from entering sensitive parts of the distribution system. By discharging these surges safely to the ground, it ensures that vital equipment such as distribution transformers, circuit breakers, and control systems remain protected.
In summary, Type I arresters are essential for safeguarding electrical infrastructure from catastrophic lightning damage. They not only minimize equipment failure and outage risks but also enhance the overall reliability and lifespan of the power distribution system.
