Electrical appliances with a rated voltage of 3kV and above are mainly used for breaking and closing conductive circuits. From 2007 to 2012, the total industrial output value of the high-voltage switch manufacturing industry increased year by year, with a year-on-year growth rate of over 10%, and the industry maintained a rapid development speed. In 2012, the industry achieved a total industrial output value of 204.009 billion yuan, a year-on-year increase of 15.74%; From 2007 to 2012, the sales revenue of the high-voltage switch manufacturing industry increased year by year, with a sales revenue of 172.09 billion yuan in 2011, a year-on-year increase of 18.96%; In 2012, the sales revenue reached 2010.21 billion yuan, a year-on-year increase of 16.87%. Compared with 2011, the year-on-year growth rate of the industry's total industrial output value and sales revenue decreased in 2012. Between 2007 and 2012, except for 2010, the production and sales ratio was less than 100% in all other years, reflecting a state of oversupply in the industry. In 2012, it was 99.64%, a decrease of 0.04 percentage points compared to 2011, indicating a more serious oversupply phenomenon in the industry. With the continuous expansion of the industry market size and industry scale, the growth rate of the industry is showing a downward trend, indicating that the competitive landscape of the high-voltage switch market has changed. The focus of the development of the high-voltage switch industry is to improve the production efficiency and service quality of the entire power industry, and strive to achieve diversification of products and services within its own field. The industry has entered a period of strategic adjustment. The strategic adjustment methods of the high-voltage switchgear industry are mainly divided into vertical extension and horizontal expansion. Among them, vertical extension refers to the deep development of the industry's scale, system, and quality, such as innovative high-voltage load switchgear technology; Horizontal expansion refers to an expansion that focuses on the scale and structure of the high-voltage switchgear industry
