The 150kA flow capacity design is adopted to meet the operation requirements of the 110kV line in the thunderstorm area and the cancellation of the ground wire.
It can directly replace ordinary line insulators and line arresters. It is easy to install and does not require special grounding treatment. It only needs to meet the natural grounding requirements of towers.
