There are more than 200 domestic line insulator manufacturers, of which about 40 have a certain scale of production. More than 100 countries in the world have adopted tempered glass insulators, with the number exceeding 200 million. Due to the acceleration of power grid construction, compared with porcelain insulators, the development of glass insulators in China is more rapid, and its market demand exceeds supply, which constantly attracts other enterprises to enter this field.
Since 2004, the main business income of major enterprises in insulator arrester industry in China has been growing rapidly and continuously, with an average annual growth rate of nearly 25%. With the improvement of the technology level of insulating products manufacturing in China and the acceleration of economic development in East and South Asia, major domestic enterprises seize the opportunity to actively explore the international market, and the export delivery value of the industry increases year by year. According to relevant research, the annual composite growth rate of sales revenue of insulator arrester manufacturing industry in China is 17.83% from 2012 to 2015. In 2015, the domestic sales revenue of insulator 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 increased year by year. According to statistics, the installed capacity of power generation in China was 962 million kilowatts in 2010, an increase of 10.08% over the same period last year. Insulator arrester, as an indispensable part of power transmission and transformation equipment, is closely related to the development of power industry.
Electric power industry is the main application market of insulator arrester products. At present, many electric power projects in our country, such as the construction and transformation of urban and rural power grid, the transmission of electricity from west to east, the construction of electrified railway and the start of UHV product market, not only provide a broad market space for the development of insulator arrester industry, but also bring forward new market for industrial products. The requirements have promoted the adjustment of market structure of insulator arrester products and the development of new technologies.
