According to industry insiders, 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 accelerated construction of the power grid, compared with porcelain insulators, the development of domestic glass insulators is more rapid, and its market is in short supply, which continues to attract other companies to compete in this field.
"At present, there are relatively many glass insulators applied on DC and AC UHV lines in China. Domestic enterprises have achieved independent innovation through years of technical reserves and experience accumulation. The advantages of glass insulator products are remarkable. First, the strength is higher, and the second is anti-pollution flash. The ability is stronger, and the third is the low self-explosion rate." The person in charge of an insulator manufacturing company said that this feature makes the glass insulators do not need [zero value" detection during operation to ensure safe operation of the grid.
In recent years, China's power industry has developed rapidly, and the installed capacity of generators has increased year by year. As an indispensable part of power transmission and transformation equipment, insulators are inseparable from the development of the power industry. In view of the practical problem that China's insulator equipment still has a certain gap with foreign countries in manufacturing technology, domestic insulator manufacturing enterprises continue to improve their research and development capabilities, and always regard independent innovation as the inexhaustible motive force for sustainable development, and adhere to the road of independent brand development.
