Generally, there are many high-voltage equipment, transformer equipment and low-voltage equipment with high voltage in the switchgear. In the switchgear, due to the large transmission voltage and conductive current, the copper wire for general conduction is not enough to ensure the smooth conduction of the current. Therefore, it is very common to use conductive plates instead of copper wires in switchgear. . Although the conductive plate can conduct a large current, it also has certain inconveniences in operation. For example, when installing the conductive plate, the conductive plate needs to be bent to facilitate the connection between the two devices.
