China's low-voltage electrical appliance market has great potential for development

In recent years, the low-voltage electrical appliance industry continues to develop rapidly. The market capacity of the low-voltage electrical appliance industry is closely linked with the development of the electric power industry. The rapid development of the domestic power grid construction has brought about a broad space for the development of the low-voltage electrical appliance industry.

The manufacture of low-voltage electrical products involves a variety of professional processes, such as cold stamping, plastic molding, coil winding, contact welding, mold processing, SMT chip technology, etc. Therefore, the improvement of low-voltage electrical product manufacturing technology and the improvement of these professional skills Inseparable.

China has become a major producer of low-voltage electrical appliances and has become a major exporter. The research and development of high-end products will remain the main direction of the industry in the future. According to the corresponding distribution equipment required for newly-increased power generation equipment during the “Twelfth Five-Year Plan” period and the needs of existing power equipment replacement and maintenance, it is expected that universal circuit breakers, plastic shell circuit breakers, miniature circuit breakers, AC contactors, and heat The demand for relays, residual current circuit breakers and other products will reach more than 200 million units.

Parts processing tends to be faster, more automated, and more specialized. Stamping parts account for a large proportion of low-voltage electrical parts, about 70%, so the processing of stamping parts occupies an important position in the production of low-voltage electrical appliances. To improve the production efficiency and quality of stamping parts, it is imperative to adopt high-speed automatic punch presses and multi-position progressive punching dies. Plastic parts are important parts of low-voltage electrical appliances, using automatic or semi-automated thermoplastic or thermosetting injection molding machines and adopting centralized feeding methods. Widely used in automated welding machines, the welding current, pressure, pulse cycle can be adjusted to maintain the temperature controllable to ensure the welding strength.

After 50 years of development, China's low-voltage electrical industry has formed a complete industrial system. Its products are widely used and have a huge market potential. According to CMIC statistics, domestically produced low-voltage electrical products have about 1,000 series, with an output value of 20 billion yuan, and more than 2,000 production enterprises with a scale above, mainly concentrated in coastal provinces such as Guangdong, Zhejiang, and Shanghai. At present, low-voltage electrical products are in the first-to-third-generation level, and the fourth-generation products are still under development.

With the improvement of the level of domestic power construction and the continuous development of low-voltage electrical production technology, a new generation of low-voltage electrical appliances featuring intelligent and communicable features will become high-end products. At present, domestic low-end and middle-end low-voltage electrical appliances basically account for most of the domestic market, but domestic high-end low-voltage electrical appliances can be shared equally with foreign counterparts except for individual products. Most of the domestic market share of products is still very low. The demand for low-voltage appliances still depends on imports.
