Electrical insulation materials are the key basic materials for manufacturing electrical (electronics) equipment, and have a decisive effect on the service life and operating reliability of electrical (electronics) equipment. With the development of my country's power industry to high voltage and long -range conveying, the quality and reliability of electrical insulation materials have put forward increasing requirements for the quality and reliability of
electrical insulation materials. The general trend of the development of insulation materials.
The role of the insulation material is to isolate different the electrostatic parts in the electrical equipment. Therefore, insulation materials should first have high insulation resistance and pressure resistance, and can avoid accidents such as leakage and breakdown. Secondly, the heat resistance is good, and it should avoid aging and deterioration due to long -term heat; in addition, it should also have the characteristics of good thermal conductivity, moisture resistance, lightning protection and high mechanical strength, and convenient process processing.
Electric insulation materials have become the need for the electrical industry.
