The role of terminals in electrical equipment

As a link between wires, terminals are widely used in electrical equipment and are indispensable, such as in complete switchgear and small three-box series. So what are its functions? In electrical equipment, the functions of terminals mainly include the following points:

Terminals have the function of connection. Terminals are used to connect the wires in the circuit to ensure that the current can flow normally. This includes the connection between the equipment inside the screen and the equipment outside the screen and the small busbar on the top of the screen, as well as the connection between the equipment of different installation units in the same screen.

Terminals not only speed up circuit connection, but also provide electrical protection for electrical equipment. For example, the use of shelled terminals can achieve a completely sealed connection, preventing electrical equipment from being damaged by foreign substances such as water and dust.

Terminals help control the input and output of current, especially in high voltage applications. Using terminals can ensure a stable connection between wires and machines, improving safety.

In addition, the use of terminals also facilitates maintenance and replacement: the design of the terminals makes them easy to install and remove, making them easy to maintain and replace, which is very important for ensuring the long-term stable operation of the equipment.

Adapt to different environments: There are many types of terminals, such as plug-in type, fence type, spring type, etc., which are suitable for different environments and needs, such as high current, high voltage environment or the need for through-wall installation.

In short, terminals play a vital role in electrical equipment, not only improving the flexibility and safety of circuits, but also facilitating maintenance and upgrades.
