Product Description

Introduction
In the 35kV power system, the post - connected arrester plays a crucial protective role. It is mainly used to limit transient over - voltages caused by lightning strikes, switching over - voltages, etc. By restricting excessive voltages within the bearable range of equipment, it effectively protects electrical equipment from the damage of instantaneous high voltages, improving the stability and reliability of the power system operation. The post - connected arrester has characteristics such as fast response speed and large current - carrying capacity, and can quickly act to release over - voltage energy to ensure the safe operation of the power system.
