What are the porcelain insulator in power transformer?
At present the insulator are almost on the transmission line, porcelain material. Porcelain insulator provides both electrical insulation and the mechanical strength/rigidity needed for the application.
Restricted by the development of science and technology, before production of the power system of insulator are porcelain insulator. Such as porcelain pin type insulator, porcelain suspension insulator, porcelain line post insulator and so on. Insulator manufacturer will often together, because in the production of insulator to use special clay.
Today, there are two alternate materials for insulators, class and silicone rubber. And it has become popular at higher voltage thanks mainly to work done with glass insulators in France. Silicone rubber insulator due to its cost and weight, has become very popular.
