Industrial plugs and sockets are a new generation of power connection devices. They are internationally practical and trustworthy, and are suitable for various applications. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. 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. 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. It is slowly used in stainless steel plate concentrator, petrochemical equipment, machinery and equipment, electric power installation project, electronic components, building engineering construction, airport, mining, quarrying plant, building water supply and drainage solution station, ports, seaports, shopping malls, hotels, gardens and public service facilities such as power transformers for machinery and equipment purchased abroad.Industrial plugs and sockets adopt gb11918 ~ 11919 ~ 2001 national standard, which is equivalent to iec60309-1, -2, en60309-1, -2 ul1682, bs4343 and other national standards. A new generation of industrial-grade plugs and sockets can industrially produce three-phase or single-phase line power transformers connected with filament machines. The industrial production plugs and sockets of different models produced and processed by the company have the design features of the outline design scheme. Although the materials are different, most specifications and models meet the practicability of the above standards. According to the application scope, installation method and waterproof grade, it can be divided into power supply and distribution system line socket and electrical equipment and instrument socket, which are respectively installed, tested and wall-mounted, universal (ip44), waterproof switch socket (ip54) and immersion socket (ip67).Color description of rated voltage of enclosure. For example, yellow stands for 110-130 V, blue stands for 220-250V and red stands for 380-419V, which is easy to distinguish. Power cord plugs and sockets with different rated voltages have different structural specifications. Yes, there are different rated voltages, frequencies and very few, and the number of hours in the grounding system is also different. That can prevent incorrect insertion of different models and specifications. The ground pole insert sleeve in the socket is longer than that of the phase pole insert sleeve, which ensures that the ground pole is connected first when the lamp line is connected, and the ground pole is finally solved when it is pulled out, which is a very safe factor. Add a plastic ferrule to the plug sleeve to ensure the high-quality touch conductivity after connecting with the power plug, and avoid damaging the plug socket due to poor contact and heat. The waterproof level is high, and it can be used under poor geographical environment specifications. Mechanical equipment is used to prevent falling, which further improves the reliability of safety factor of connection between power cord plug and socket power transformer.This product adopts high-quality rubber and plastic product polyester cloth (PA66) as the shell, which has high tensile strength, impact resistance and fear of falling and climbing, and solves the shortcoming that old plugs and sockets are easy to fall, and is suitable for all kinds of places.The new generation of industrial-grade plugs and sockets and their applications, with high safety and reliability, quick installation and connection, convenient and quick insertion, simple operation process, low model, specification, quality and price, are suitable for users to choose models and specifications, are in line with international standards, and have been widely used.
