Low-voltage electrical appliances is a signal based on the outside world and requirements, from the construction of smart grid to the current booming new energy industry, and then from the power industry to the lively construction industry, low-voltage electrical appliances in China has gone through more than 50 years of history . With the rapid growth of urban population and the increasing demand for electricity, the market for low-voltage electrical appliances will continue to expand in the future. It is estimated that the market size of low-voltage electrical appliances in China will reach 75 billion yuan by 2015, and the market growth will reach about 20%. Although the low-voltage electrical market has a vast market space, but for now, China's low-voltage electrical market is chaotic. It is reported that the domestic low-voltage electrical manufacturing enterprises small, too many, more than 90% of enterprises in the middle and low-grade products of the repeat production, the market product "three generations co-exist." Intelligent has been regarded as low-voltage electrical industry transformation and upgrading of an important step, both the relevant departments or industry bodies, will be regarded as the future direction of development of low-voltage electrical appliances industry. With the continuous development of low-voltage electrical production technology, intelligent, modular, communicable as the main characteristics of a new generation of intelligent low-voltage electrical appliances will become the mainstream products. High-end low-voltage electrical appliances market share will be further expanded. Intelligent requirements of low-voltage electrical appliances application of intelligent manufacturing technology and equipment, including the establishment of key components of automated production lines, low-voltage electrical automatic detection line, low-voltage electrical automatic equipment lines. During the "12th Five-Year Plan" period, China will optimize the power structure and strengthen the construction of smart grid, and the market demand for power equipment will rapidly increase. Relevant data show that the State Grid will invest 1.5 trillion yuan in the construction of smart grids and smart grids, or about 300 billion yuan annually, which will ensure the steady growth of low-voltage electrical appliances during the "12th Five-Year Plan" period . 2014-2020 will be the major period for China's smart grid construction. The total investment of smart grid is estimated to be nearly 4 trillion yuan. The smart grid has entered an important stage of overall construction. The intelligent construction of urban and rural distribution networks will be fully opened. The smart grid and intelligent complete sets of equipment, intelligent distribution and control systems will usher in a golden period of development. This will accelerate the upgrading of low-voltage electrical products in our country and the re-division of the low-voltage electrical market.
