With the demand of the downstream market, the industrial plug develops well. CEE connector CEE standard industrial plug socket is an explosion-proof socket, and the temperature is limited below 32 degrees. 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. 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. With the development of industry, consumers' requirements for industrial plugs are gradually increasing, which urges domestic industrial plugs to be closer to the characteristics of products in the new era, such as multifunction, humanization and modularization. However, domestic industrial plug manufacturers should assess the situation and understand the consumer's consumption tendency and demand, so as to continuously develop and develop industrial plug products that meet the consumer's demand.Compared with the past, domestic industrial plugs have made a qualitative leap. The quality and performance of industrial plugs cannot be compared with those of previous years, and the types of products are constantly improving to meet the requirements of on-site power connection under various environmental conditions. From the improvement of industrial plug quality, we can directly feel the development of domestic industrial plug manufacturers. With the development of China's industry, domestic industrial plug manufacturers have also entered a period of rapid development. Industrial plug is a basic component in the field of industrial power distribution. It is connected with industrial plug to provide power and energy for electrical equipment, and it is an indispensable product in various domestic industrial places. Therefore, the market demand in China is huge, which provides a huge living space for domestic industrial plug manufacturers, and the number of industrial plug manufacturers is gradually increasing. Every industrial power plug manufacturer wants to gain market share, which directly leads to more and more fierce competition between manufacturers. They are constantly improving their competitiveness and innovating some existing technologies under the guidance of the high quality of industrial plugs. Benign competition is beneficial to users and industry. High quality industrial plug products can benefit users and promote the development of industrial plug industry.It is hoped that with the development of our country, domestic industrial plug manufacturers will continuously increase the added value of industrial plugs and improve their quality, so as to provide a high-quality and high-performance industrial plug for the industrial power distribution field of our country and even the whole world.
