Editing and broadcasting of Industrial Development
There are nearly 200 line insulator manufacturing enterprises in China, including about 40 enterprises with a certain production scale. More than 100 countries in the world have adopted tempered glass insulators, with the number exceeding 200million. Due to the acceleration of power grid construction, compared with porcelain insulators, domestic glass insulators are developing more rapidly, and their market supply exceeds demand, which continuously attracts other enterprises to enter this field.
Since 2004, the main business income 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 products 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 increases year by year. According to relevant research forecasts, the compound annual growth rate of the sales revenue of China's insulator arrester manufacturing industry from 2012 to 2015 is 17.83%. In 2015, the sales revenue of China's 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, China's installed power generation capacity in 2010 was 962million kW, a year-on-year increase of 10.08%. As an indispensable part of power transmission and transformation equipment, insulator arrester is closely related to the development of 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 construction of electrified railways and the launch of the UHV product market, not only provide a broad market space for the development of insulator arrester industry, but also put forward new requirements for the industrial product market, It has promoted the adjustment of the market structure of insulator arrester products and the research and development of new technologies.
