Development of Insulator Industry

There are nearly 200 domestic manufacturers of line insulators, of which about 40 have a certain production scale. More than 100 countries around the world have adopted tempered glass insulators, with a quantity exceeding 200 million pieces. Due to the acceleration of power grid construction, compared to porcelain insulators, the development of domestic glass insulators is more rapid, and their market supply is in short supply, constantly attracting other enterprises to compete and enter this field.
Since 2004, the main business revenue of major enterprises in China's insulator and lightning arrester industry has continued to grow rapidly, with an average annual growth rate of nearly 25%. With the improvement of the technical level of China's insulation product manufacturing industry and the acceleration of economic development in East Asia, South Asia and other countries, major domestic enterprises seize the opportunity to actively explore the international market, and the export delivery value of the industry has been increasing year by year.
According to relevant research predictions, the annual compound growth rate of sales revenue in China's insulator lightning arrester manufacturing industry from 2012 to 2015 is 17.83%. In 2015, the sales revenue of the domestic insulator lightning arrester industry will reach 40.3 billion yuan.
In recent years, China's power industry has developed rapidly, and the installed capacity of generators has been increasing year by year. According to statistics, the installed power generation capacity in China was 962 million kilowatts in 2010, a year-on-year increase of 10.08%. Insulator lightning arrester, as an indispensable component of transmission and transformation equipment, is closely related to the development of the power industry.
The power industry is the main application market for insulator lightning arrester products. At present, many power projects in China, such as the construction and renovation of urban and rural power grids, the West East power transmission project, the electrified railway construction project, and the launch of the ultra-high voltage product market, not only provide broad market space for the development of the insulator lightning arrester industry, but also put forward new requirements for the industry product market, promoting the adjustment of the market structure of insulator lightning arrester products and the research and development of new technologies.
