Nowadays, the industrial plugs and sockets produced by manufacturers in the market have been widely praised in the market, which has aroused the pursuit of many customers. This is mainly because the industrial plugs and sockets produced are very safe and reliable in use, mainly reflected by the following aspects. Industrial plugs are suitable for industry, generally divided into 3-core, 4-core, 5-core, etc. The current is generally divided into 16A, 32A, 63A, 125A, 250A, 420A, etc., and the protection level can be divided into IP44 and IP67, which are relatively conventional. Generally, it is used with industrial sockets and industrial connectors. A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. The power socket has one or more seats into which circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits.1. First of all, the rated voltage of the shell color of this product should be distinguished, blue is 220v, and red is 380v, so people with certain product knowledge can quickly distinguish products without mistakes in application.2. The difference between various specifications of this product is very obvious, and it is not the same in diameter, pole number and grounding contact position, so it is impossible to plug between different specifications in application, which also prevents some wrong plugging operations.3. This product has the function of electric shock protection. In the design and production of this product, the grounding electrode socket is longer than the middle grounding electrode socket, which ensures that the grounding electrode is firstly grounded in the subsequent use process, and finally the grounding electrode is protected when the fault is pulled out, and finally the grounding electrode is separated from the grounding electrode, thus ensuring the safety of equipment use.4. The product has a very high level of protection, and can be used in a variety of harsh environments without being affected, safe and normal.5. The socket of this product is equipped with elastic hoop, which ensures that the equipment is connected very tightly in the plugging process, will not be separated, and can supply power normally. Other holding devices and holding devices, and for the equipment in use, the components will not be separated from each other, so as to ensure the reliability of use and improve the safety of use.These are some reasons why industrial plugs are so widely used, because they are very safe to use and can maintain high stability of equipment.
