Almost everyone is familiar with the product of industrial plug. Many fire accidents are basically caused by the fact that the material of industrial plug is not particularly good. Don't underestimate this small industrial plug. If there is any material problem, it will easily pose a threat to the lives and property safety of many users, and the consequences are unpredictable and serious. Therefore, it is very important to pay attention to this problem. Therefore, the quality of industrial plug is the first priority. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. 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. 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. When selecting and purchasing this kind of products in the market, the safety performance of industrial plugs must be considered. The general performance standards of industrial plug products are as follows: 1. Industrial plugs should have signs indicating voltage, current and other performance parameters, etc. Signs mainly refer to the use, installation and maintenance of data, which can greatly guarantee the safety standards of property and life. Signs must be placed in conspicuous places. This product of industrial plugs must be marked with rated power supply and current. This is mainly to prevent users from overloading. It is also important to note that the signs of industrial plugs should be durable and look very clear from the surface of the signs, and the signs must not be easily erased. 2. The rating of industrial plugs is also very important. The rating must be used safely with the connector. The parameters and ratings of the connector are very basic, and the current of the device used should not exceed the current of the industrial plug, otherwise the user will easily overheat the current in use, which will easily lead to more serious danger of one kind or another. 3. The overall size of the industrial plug is also very important. It is safer and more interchangeable in actual use. These are closely related to the size of the industrial plug. What's more, it is also related to the size of the industrial plug to prevent misoperation. These are the basic technical requirements of the industrial plug in actual use. If the size of the industrial plug does not meet the basic requirements, This will directly affect users. In actual use, it is easy to happen the situation of wrong insertion and poor contact, etc. If it is not too serious, it will cause the equipment to be unusable, and if it is serious, it will cause electric shock and fire. 4. Protection against electric shock of industrial plugs is a very important function. Protection against electric shock means that under normal or slightly abnormal conditions of industrial plugs, users will not get an electric shock accident at all. It can also be said that protection against electric shock of industrial plugs is a very important safety index, and it should be noted that live parts cannot be touched.
