What are the functions and applications of the terminal box Việt Nam

The main role of the terminal box is to achieve electrical connection, it is usually made of plastic, metal or other materials, with multiple terminals and outlets, for access to power lines and electrical equipment, due to commissioning, maintenance and other factors, the wire in this position needs to be frequently disassembled and assembled. For example, two wires, sometimes need to be connected, sometimes need to be disconnected, and then can be connected with a terminal box, without welding or winding together can be disconnected at any time, in the automated production line of various sensors, actuators and controllers and other electrical equipment need to be stable and reliable connection, and terminal terminals are the key to achieve these connections. They ensure the accurate transmission of electrical signals and energy, thus guaranteeing the normal operation of the production line.

Terminal box is widely used in some applications that require threading solutions: power supply, industrial automation, new energy, transportation, electrical control cabinets and other electronic equipment. The insulation performance is good, the protection level is high, and the user only needs to work directly after the external wiring, eliminating many unnecessary wiring steps.

So, what knowledge do we need to know when purchasing terminal boxes

1.  How many A terminals are needed inside, we can get A number according to power/voltage = current.
2. Do we need to open holes to do in and out of line processing, how many in and out? We need to know how many lines go in and out if we need to. For example, we need a four-in junction box, and our line is 3*2.5 square, then the standard configuration, we need 12 terminals, the specific algorithm (four *3 cores =12)
3. The most important thing is the diameter of the incoming line and the outgoing line, because the waterproof joint should be equipped according to the line diameter. Others should be judged according to their own use environment, use scenario, level, box size, these need to be selected by themselves.

All in all, junction boxes are very important equipment in electrical engineering, with a variety of roles such as centralized management and protection of cable connections, supply of power and signal transmission. It can not only improve the overall management and maintenance efficiency of the electrical system, but also protect the cable connection and equipment safety, improve the stability and reliability of the system, and reduce engineering costs. In electrical engineering, junction boxes play a vital role as the basis for the normal operation and safe use of electrical systems.
