E-glass fiber and its products have a range of excellent performance because

The transformer is an important power industry for substation equipment, ensure that the transformer operation safety and reliability, not only for the promotion of economic development and social progress of great significance, but also to ensure that people's lives and property also has a very important significance. E-glass fiber and its products because with a series of excellent performance, especially good  power transformers , high heat resistance, has been in power electrical industry has been widely used. In recent years, due to the power transformer and technological progress and product upgrading, glass fiber and its products in the manufacture of dry-type transformers, has become an indispensable important material.  air circuit breaker  of the development since the Faraday discovered electromagnetic induction has been more than a century ago is the earliest of the transformer dry-type transformers. Because of this transformer can not be bigger, high voltage can not do technically was extremely restricted. The emergence of  electric transformer technology development made an indelible achievements. Currently, the transformer industry mainly to produce mainly oil-filled transformers, which accounts for about 60% of total capacity to 70%. In the use of oil-filled transformers have some fatal disadvantages, limiting its wide application.
