Is it imperative to promote the development of the insulatio
As a basic material, insulation materials have a wide range of applications, such as the power industry, which is the lifeline of the national economy. Its development is closely related to high-performance insulation materials. Insulation material is a key material to ensure the reliable, durable, and safe operation of electrical equipment, especially power equipment. Its level will directly affect the development level and operation quality of the power industry. With the development of the economy, the maximum voltage level of transmission lines in China will be increased from 500kV to 750kV or 1000kV, and for every step increase in the voltage level of transmission lines, the insulation system of power equipment must also be correspondingly improved. Without high-performance insulation materials as a guarantee, local power grid instability may occur from power generation, transmission and transformation to all power systems, and in severe cases, the entire power grid may be paralyzed. Therefore, the progressiveness and stability of insulation materials are of great significance in ensuring the reliability and stability of power generation, transmission and transformation, and the operation of electric equipment. For national defense, insulation materials are required for power, control, communication, radar and other systems in military equipment. To develop new military equipment, there must also be new insulation materials as a precursor. For example, nuclear submarines require insulation materials that are resistant to salt spray, moisture, mold, and radiation, while aerospace vehicles require insulation materials with high dimensional stability, low temperature resistance, and radiation resistance. If insulation materials cannot meet the stringent requirements of these harsh operating environments, it will result in many important systems in military equipment not functioning properly.
