Organic insulating materials are: shellac, resin, rubber, cotton yarn, paper, hemp, rayon and so on, mostly used to make insulating varnishes, winding wires, such as covering insulation. The composite insulating material is made from the above two kinds of materials through the processing of various molding insulating materials, which are used as the base and housing of electrical apparatus.

Margin materials are graded, insulation grade and insulation material temperature resistance is closely related, the higher the temperature insulation material insulation grade performance, so insulation materials have a temperature-resistant performance standards, within the standard can be assured of use. Insulating material grade generally divides into 3 kinds: the gas insulating material insulation grade: Has the air insulation, the nitrogen insulation and the sulphur hexafluoride insulation general gas insulation under the discharge voltage has the very strong insulation resistance, and if the occurrence insulation damage also can automatically restore. Compared with liquid insulation and solid insulation. The yield value of insulating grade is low. Therefore, the requirements of it are: Have a good free field strength and breakdown strength, and after the breakdown of its insulation performance can be quickly, automatic reduction. belongs to the elastic
