Standards And Specifications For The Performance Of Insulating Bushings In Different Countries

Insulating bushings are an integral part of power engineering, and their performance standards and specifications are highly valued in countries around the world. Different countries have formulated unique insulating bushing standards and specifications based on their own power system characteristics, environmental conditions and technical levels to ensure the safe operation and reliability of the power system.

USA

As one of the leading countries in power engineering technology, the United States' insulation bushing performance standards and specifications are formulated and managed by the American National Standards Institute (ANSI). ANSI C37.50 is an insulating bushing standard formulated by the Institute of Electrical and Electronics Engineers (IEEE), which includes the design, testing and performance requirements for insulating bushings. In addition, the United States has also formulated various insulating casing standards such as NEMA TC 7, ASTM D2513, etc. based on different uses and occasions to meet different needs.

Europe

European countries mainly base their performance standards and specifications on insulation bushings on the standards of the International Electrotechnical Commission (IEC) and the European Committee for Standardization (CENELEC). IEC 60502-1 is the most commonly used insulation bushing standard in European power systems, which includes requirements for insulation materials, structures, test methods, etc. In addition, European countries will refine and supplement according to their own national conditions and technical levels, such as Germany's DIN VDE standard and the British BS standard.

China

As one of the countries with the largest electricity demand in the world, China's insulation bushing standards and specifications are formulated and managed by the State Power Corporation and the Standardization Administration of China (SAC). GB/T 12706 is an insulating bushing standard widely used in China's power system. It includes requirements for the structure, materials, and test methods of insulating bushings. In addition, China has also formulated a series of local standards and industry standards based on the needs of different regions and industries to adapt to the needs of different environments and usage conditions.

Japan

As one of the leading countries in technological innovation and engineering quality management, Japan's insulation bushing standards and specifications are formulated and managed by the Japanese Industrial Standardization Committee (JISC). JIS C 3306 is a standard for insulating bushings commonly used in Japanese power systems. Its content is similar to IEC 60502-1, but it also has some Japan-specific requirements and regulations. In addition, Japan will continue to update and improve relevant standards based on its own technical level and needs to ensure the safe operation and reliability of the power system.

To sum up, although the standards and specifications for the performance of insulation bushings in various countries around the world are different, they are all committed to ensuring the safe operation and reliability of the power system and promoting the development and progress of power engineering technology. In the context of globalization, countries also need to strengthen exchanges and cooperation to jointly promote the development of insulation bushing technology and contribute to the sustainable development of human society.
