          Low-voltage apparatus is changing

          The third generation of low-voltage electrical products represented by DW45 represents the best level in China's low-voltage electrical industry. It is expected that it will be replaced by the fourth-generation low-voltage electrical products featuring communication. In order to speed up the realization of the goals of meeting different levels of market demands, keeping pace with the world's cutting-edge technologies, and surpassing the EU barriers, the development of a new generation of products has become a top priority.

          The trend of a€?new generationa€? is introduced to meet the diversified needs at different levels. After years of development in China's low-voltage electrical industry after the '85', the third-generation low-voltage electrical products represented by DW45 have been formed. Its basic features are high performance and miniaturization; electronic, intelligent, modular, and multi-functional. Most of the products have been developed and put on the market, becoming China's current high-end products in the low-voltage electrical industry.

          With the continuous development of new technologies, new materials and new standards in the low-voltage electrical appliance industry, by 2010, China's first-generation products will be completely phased out. Second-generation products will become low-end products, and third-generation products will be reduced to mid-range products. To this end, from the perspective of product development and market requirements at different levels, it is necessary to develop the fourth generation of low-voltage electrical products.

          Track the need for new product development and market competition in foreign countries. At present, the major foreign manufacturers of low-voltage electrical appliances such as Schneider, Siemens, ABB, Moeller, GE, Cutler, Hammer, Mitsubishi, and Fujitsu have all launched a new generation of products from the late 1990s to the beginning of this century. Whether from the comprehensive technical and economic indicators of products, product structure and material selection, as well as the application of new technologies (such as digital and communications technology), there have been new breakthroughs. There are signs that a new generation of products has begun to enter the Chinese market. In order to win market competition, the development of a new generation of low-voltage electrical products in China must be accelerated.

          Change the difference in the 'quality' of the product's function and inject high-tech into traditional low-voltage electrical appliances. With the development and application of fieldbus technology, low-voltage electrical products are being developed for communication and networking. At present, most of the latest generation of foreign products have a communication function, and the development and application of the third generation of low-voltage electrical products in China has shortened the gap between China's products and foreign advanced level to ten years or so, if low-voltage electrical communication technology is not timely Keeping up, then the gap with the advanced level in foreign countries is not only the difference in product performance, but the difference in product quality. It will make China's low-voltage electrical equipment completely lose market competitiveness in the future intelligent low-voltage power distribution and control systems. It can be said that the fourth generation of low-voltage electrical appliances with main features of communication will be the direction of future industry product development.

          Develop 'green' and cross the EU barriers. With the promulgation and implementation of the EU's two environmental directives, it means the arrival of ecological appliances, the era of 'green' appliances. The EU market requires that electrical products be designed, produced, used, and recycled to consider whether they affect the ecological environment. In fact, many products currently produced in China do not meet the requirements of environmental protection directives. To this end, it is necessary to eliminate the traditional products, from the beginning of product design to consider the selection of new materials, manufacturing processes to comply with EU directives, so that China's low-voltage electrical appliances gradually become 'green' products.

          Fortunately, in recent years, China's low-voltage electrical manufacturing process has greatly improved the level of automatic online product testing has begun to apply, in order to adapt to the development of new technology, but also need to vigorously develop a new generation of products.

          Changing the pattern of the third generation of the same generation of the low-voltage electrical appliances of the fourth generation will make a significant change in the product structure of the low-voltage electrical appliance industry in China, thus changing the current pattern of low-voltage electrical appliances for three generations.

          The "new generation" products can be connected with a variety of open and advanced fieldbuses in the world to meet the needs of low-voltage power distribution and control system networking. According to different products can be directly connected with the bus system, can also be connected through the communication adapter, its comprehensive performance can reach the advanced level of the latest generation of foreign products.

          The product has four main features: high performance, set key breakthrough targets for major technical indicators of different products, these indicators have significantly improved over the third generation products;

          Can expand and improve, with the universal application of microprocessor and communication technology in a new generation of low-voltage electrical appliances, product features will be further expanded and improved; high reliability, improve reliability is one of the main goals of the fourth generation of products, from Comprehensive considerations in product design, material selection, manufacturing process, product testing, etc., and the development of internal reliability assessment indicators and assessment methods; improve product maintenance performance, user-friendly use is one of the pursuit of a new generation of foreign products, China's fourth generation Low-voltage electrical appliances and the development of new products in the future will also give full attention to this.

          The development of the fourth-generation low-voltage electrical appliances will also achieve significant innovations in product structure: First, there will be new breakthroughs in overall product plans, structural layout, and major component structures. Second, the degree of product modularity has been significantly improved compared to the third generation of products. Third, accessories, accessories, and connection methods are complete to meet the needs of different users. Fourth, the appearance of a new generation of low-voltage electrical appliances has significantly improved. Fifth, the selection of the main materials for the fourth-generation low-voltage electrical appliances meets the requirements of environmental protection and meets the requirements of the EU's two environmental protection directives that specify the restrictions on the use of lead, mercury, cadmium, hexavalent chromium, polybrominated diphenyl ethers and polybrominated biphenyls in electrical equipment. The requirements of six kinds of hazardous materials, so that China's low-voltage electrical appliances gradually to the development of environmental protection appliances. Sixth, the structure and assembly of the fourth-generation low-voltage electrical parts and their assembly and testing should be adapted to the requirements of automated production.

          At present, China's low-voltage electrical production scale and manufacturing levels have initially adopted the requirements of automatic assembly and automatic testing. To this end, in the design stage of new generation products, we must consider the technical requirements in this area, and lay the foundation for the improvement of the overall level of low-voltage electrical appliances in China.

          There will be major changes in product structure. In the coming period, the development direction of China's low-voltage electrical industry will be further intelligent and communicative. Low-voltage power distribution and control systems will gradually develop into intelligent networks.

          Accelerating the R&D and promotion of the fourth-generation low-voltage electrical appliances in China will be the focus of the industry's work in the coming period. From 2010, China's fourth generation of low-voltage electrical appliances will be gradually put on the market, and the overall level of the industry has already reached a new level. According to the market demand, some third-generation products will be further developed to further improve the cost-effectiveness, and at the same time achieve product differentiation and improve product market competitiveness.

          It is worth mentioning that the development of new products should draw on the advanced experience of foreign countries. When a well-known foreign company develops new products, it should take into account both high-performance and economic models to meet the needs of different market levels. According to this, China's new generation of products should develop economic products at the same time when deriving third-generation products or developing fourth-generation products.
