What materials are solid insulation materials?

We all know that insulating materials can be simply divided into solid, liquid and gas three categories, which are usually used in more or solid insulation material, as long as it can be isolated from the potential of the conductor as a solid can be Classified as this category.
Compared to gas phenolic paper sheet and liquid insulating materials, the density of the solid insulating material is relatively high, so it has a high breakdown strength and helps to reduce the insulation thickness. The solid insulation material itself can also be divided into two kinds of inorganic and organic.
Wherein the inorganic solid electrical insulating board comprises mica, powder mica and mica products; glass, glass fiber and its products, and electric porcelain, alumina film, respectively, for different insulation structures. But they have a common characteristic, such as high temperature, not easy to aging, with considerable mechanical strength.
Inorganic solid insulation material is not perfect, its main drawback is poor processing performance, so this material is not easy to adapt to the electrical equipment on the molding requirements of insulating materials. It is precisely because of this, but also limits the scope of application of inorganic solid insulation materials to further expand.
Let's talk about organic solid insulation materials, just when there are some natural materials, such as paper, cotton, silk, rubber, can be cured of vegetable oil. But with the advancement of technology, synthetic polymer materials fundamentally changed the form of organic solid insulation materials.
And the elastomer material is also gradually to the insulation side of the line, such as heat-resistant silicone rubber, oil-resistant nitrile rubber, and the subsequent fluorine rubber, ethylene propylene rubber, etc., are very typical organic solid insulation materials
