Today, I'm going to tell you about the classification of industrial plugs. Do you doubt that the classification of industrial plugs is not common fixed type and mobile type?Originally, the common fixed industrial plug is a wall or floor version of the installation socket, which can not be moved for installation. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt commutation device quickly and braking device effectively. 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. 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. Generally speaking, in this case, there are relatively few connection points of power outlets installed, and the possibility of temperature rise at the connection points is small, so the safety factor becomes high. Some electrical appliances in corners of the home that don't need to be moved will try to use fixed industrial plugs. Fixed industrial plugs are divided into light-colored and dark-colored ones, and families with more installations are generally selected.Mobile industrial plug, which can be moved at any time according to different needs. This kind of industrial plug is closed and fixed, which is much more convenient to use. However, such mobile industrial plugs move more times, which increases the possibility of causing a great deal of damage. This portable industrial plug increases the number of connections with electrical appliances, which in turn increases the possibility of heating, making them unsafe. With the increasing number of household appliances, mobile industrial plugs will appear in almost every family. Has become a necessity for every family.The above is a classification method of industrial plugs. Let's tell you another classification method of industrial plugs:1. The national standard hole mobile industrial plug, such sockets are divided into multi-position and one-position, including two-pole grounding pass, two-pole pass and two-pole double-support pass.2. "Multifunctional" hole type mobile socket, which is very popular in the market.
