Compared with ordinary plugs and sockets, industrial plugs have advantages in industrial application, which provides safety guarantee for industrial development. Industrial plugs have many characteristics and wide application range, and have a high status in industry and obvious importance. Moreover, they work well as a bridge. A socket into which one or more circuit wires can be inserted, through which various wires can be inserted to facilitate connection with other circuits. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. IP54, i.e. dust prevention is level 5: dust intrusion cannot be completely prevented, but the amount of dust intrusion will not affect the normal operation of the product; Waterproof grade is Grade 4: prevent splashing water from intruding and prevent splashing water from all directions from intruding. As we all know, plugs and sockets are the last mile of all power consumption system software, and all temporary mobile power consumption must be handled by plugs and sockets. In traditional plug and socket, generally, the larger current is not easy to exceed 25A. If other factors such as moisture resistance are not discussed, the output power of light consumption cannot be ensured. Typical scenes include buildings, various temporary performances, stage tours, and power consumption. In the absence of industrial plugs and sockets, all the original cables are immediately connected to the bottom of the isolating switch of the distribution cabinet, which brings inconvenience to the actual operation, and there is no connection in the middle, and it is even more inconvenient to operate the general power switch. In addition, the industrial plugs can be conveniently connected in sections, which not only ensures the safe power base, but also ensures a certain degree of usability. Today, the most waterproof ip67 products on the market can be soaked in water, and the waterproof level is very high. On the Internet, we randomly found some temporary power sources in construction sites, and the clarity was not very good. We felt that. With the country attaching great importance to safety in production, industrial plugs have fully played a certain role in the application of temporary mobile power consumption, thus better ensuring the safety of power consumption.
