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. 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. 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.We can almost see the existence of industrial plugs in industrial places where electricity is used. We can't say that all industrial areas that use electricity use industrial plugs, but we believe that the coverage rate is not low. First of all, because the civil plug can not be used in industry at all, it will cause damage to electrical equipment, and there may be serious problems such as short circuit and fire. Second, it is about the safety measures of industrial plugs, which can't be done by civil plugs and sockets. The above materials are professional special materials with certain safety. The corresponding industrial plug can be used in even more dangerous and extreme situations, such as higher or lower temperatures, or situations where dangerous situations are more likely to occur.Industrial plugs have very strong universal performance, which is not only applicable to domestic standards, but also universal to international standards, so both domestic and imported products can safely use industrial plugs.In addition to some industrial equipment, it will also be used as an industrial plug to install wiring connection, such as some cabinets, lighting, air conditioning, etc., which has a wide range of applications in the construction and machinery industries. Some factories also need to use industrial plugs for conversion. As long as the equipment used is 380v voltage, the same 380v industrial plugs must be used.There is also a waterproof industrial plug. As long as there is an environment where water is used in industry, whether it is steam, rain or soaking in water, it is necessary to choose waterproof industrial plugs. In addition to industry, many urban buildings hang lights on roadside trees, and the lights at night are very beautiful. At this time, the connections are also used in waterproof industrial plugs. Many people may not notice these small places, which can reflect the wide application range of waterproof industrial plugs. Waterproof industrial plugs have different degrees of protection, which we call ip. Different degrees of protection are used to determine the environment suitable for waterproof industrial plugs, for example, they may be splashed or need to be soaked in water. The degree of protection in this way is different.
