Application Summary AI generated
GB/T 22674-2008 specifies the technical requirements, test methods, and acceptance criteria for bushings used in direct current (DC) electrical systems. It applies to bushings designed for DC voltages in power transmission and distribution equipment, such as converters, transformers, and switchgear in high-voltage direct current (HVDC) systems. This standard ensures reliable insulation and performance under DC stress conditions, particularly in industrial and utility applications where stable DC operation is critical.
