Industrial development of insulators

There are nearly 200 line insulator manufacturing enterprises in China, and about 40 companies with a certain production scale. More than 100 countries in the world have used tempered glass insulators, more than 200 million pieces. Due to the acceleration of power grid construction, the development of domestic glass insulators is more rapid than that of porcelain insulators.

Since 2004, the main business income of major insulators in China's insulator 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 products manufacturing industry and the acceleration of economic development in countries such as East Asia and South Asia, major domestic enterprises seized the opportunity and actively explored the international market. The export delivery value of the industry has increased year by year. According to relevant research forecasts, the annual compound growth rate of sales revenue of China's insulator lightning arrester manufacturing industry in 2012-2015 is 17.83%. In 2015, the domestic insulator lightning arrester industry sales revenue will reach 40.3 billion yuan.

In recent years, China's power industry has developed rapidly, and the installed capacity of generators has increased year by year. According to statistics, in 2010 China's power generation installed capacity was 962 million kilowatts, an increase of 10.08%. Insulator arresters are an indispensable part of power transmission and transformation equipment and are inseparable from the development of the power industry.

The power industry is the most important application market for insulator arrester products. Many power projects in China at this stage, such as the construction and transformation of urban and rural power grids, the west-to-east power transmission project, the electrified railway construction project, and the launch of the UHV product market are not only the insulator arrester industry. The development provides a broad market space, and also puts forward new requirements for the industry product market, and promotes the adjustment of the market structure of insulator arrester products and the research and development of new technologies.
