In recent years, the low-voltage electrical industry has seen unprecedented opportunities for development. It is estimated that the annual installed capacity will be 21 GW from 2001 to 2010. According to the empirical matching ratio, about 480,000 low-voltage frame breakers and 4.82 million molded case breakers are needed each year. In addition, the state encourages the export of mechanical and electrical products, and the export volume has increased steadily. Therefore, the market capacity of China's low-voltage electrical appliances is huge, and it is in a rising stage, and the prospects are very optimistic.
Market structure
China's low-voltage electrical industry from simple assembly, imitation manufacturing to self-developed design, now ABB low-voltage electrical appliances developed to nearly 1,000 series, about 1,500 production companies, with an annual output value of about 20 billion yuan.
However, the domestic low-voltage electrical appliance production enterprises are small and the number is too large, and more than 90% of the enterprises are in the repeated production of medium and low-grade products. The three generations of products coexist, according to the output value, the market share of the first generation products is 15%, the market share of the second generation products is 45%, and the market share of the third generation products is 40%. According to the national policy, the structure of low-voltage electrical products needs further adjustment in the future. Products that are backward in process, large in size, high in energy consumption and polluting the environment will be eliminated. It is expected that in 2010, the first generation of products will be eliminated, the second generation of products will become low-end products, and the third generation products will gradually become mid-range products.
Just as we accelerated the development of the third-generation products and brought them to the market, a number of well-known foreign low-voltage electrical appliance manufacturers launched a new generation of products from the late 1990s to the beginning of the 21st century. Among them, the frame circuit breakers have Schneider MT series, Siemens 3WL series, ABB company E series, GE company M-PACT series, Kama company Magnum series, etc.; molded case circuit breakers include Schneider NS series, Siemens 3VL series, ABB company Tmax series, GE company Record plus series, Moeller's NZM series, Kama's G series, and Mitsubishi's WS series. In addition to high-performance, electronic, intelligent, modular, combined, and miniaturized features, the new generation of products also features features such as communication, high reliability, good maintenance performance, and environmental compliance. In particular, a new generation of products can be connected to the fieldbus system to achieve system networking, which has made a qualitative leap in the function of low-voltage electrical products.
