It is incorrect to think that household plugs and industrial plugs and sockets are the same product. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. 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. IP54, that is, 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 4: prevent splashing water from invading, and prevent splashing water from all directions from invading. Industrial plugs and sockets are used in industrial production, the use environment is relatively poor, and the intersection of products with other ordinary plugs and sockets is very different.1. Safe and reliable(1) The rated voltage of these products is indicated by the color of the shell. Blue means the rated voltage is 220v, and red means the rated voltage is 380v. Two colors, easy to identify, easy to distinguish, not easy to confuse.(2) Electric shock protection design. The grounding electrode in the socket is longer than that of the positive and negative sockets, which ensures that the grounding level of the socket is switched on before the electrical appliance is switched on, and the grounding electrode is disconnected when it is pulled out. This design is very safe to use.(3) High protection level. Live parts are highly protected by protective materials, so that people can't touch the electric shock parts, and they can also be used in harsh environments.2. Good durability(1) The industrial plug socket shell is molded by one-step casting with high-quality PC raw materials, and the product is firm, resistant to falling, not afraid of stepping on, and has strong aging resistance, and can be used indoors and outdoors.(2) The product is heat-resistant and flame-resistant. And the insulation parts inside the shell are all made of heat-resistant and flame-resistant materials, and the temperature can be up to 100 DEG C without burning.3. Strong versatilityThe products meet the general standard of national electrical appliances 2002, with many specifications and models, and can fully meet various places such as industrial production and outdoor electricity use.Although China's industrial plug and socket industry started late, with its unique advantages, it gradually attracted the attention of users. After continuous popularization and application, industrial plugs and sockets have been widely used in enterprise production, power transmission, ports and other industries.
