Insulator is a kind of insulation control, play an important role in the overhead transmission lines, which have the effect of support wire and prevent the current back.
Insulator for more pole before, now has gradually developed into hang on one side of the high voltage wires disc insulator
s, usually made of ceramic or glass.
Insulator to ensure that the changes in environment and electrical load conditions, a variety of mechanical and electrical stress remains the same, otherwise don't function not only, it will damage the service life of the whole line.
< P> champ consulting mechanical industry analysts pointed out that the insulator industry in our country, in addition to lightning arrester run more smoothly, and the hollow insulator has made big progress, casing products most problematic.
According to statistics, insulator failure rate is 0.
3 ‰, the high voltage part of 0.
1 ‰, glass and porcelain insulator is 0.
So each production enterprises need from design, raw materials, process, etc, to further strengthen quality control, and strengthen the communication with the demand, develop continuously meet the demand of power grid construction in the new product, make a certain contribution for the construction of smart grid.
< / P> < P> insulator industry in the process of rapid development, there are two problems need to solve: the first, small enterprise scale, industry concentration degree is low, the industry is 'loose';
Second, base material development affects the insulator technology progress, still need to strengthen research and development.
After recent years of development, our country of insulator products quality level had the very big enhancement, good to meet the requirements of the development of China's power grid and its manufacturing has reached international advanced level, performance is getting better and better.
< / P> < P> according to champ consulting issued the 2011 China high voltage insulator industry analysis and investment outlook report shows that in recent years our country electric power industry development has brought unprecedented opportunities to the development of the insulator industry, industry enterprises should grasp the opportunity, relying on technological progress and strengthen quality management, to meet the demand of the electric power industry, especially high-grade hollow porcelain insulator and casing products market demand.
Along with our country the development of the smart grid construction and reform of city network, insulator increased demand, the market has huge potential and good prospect of development.
