GB/T 25083-2010
ActiveMetal-oxide surge arresters without gaps for ±800kV UHVDC systems
±800kV直流系统用金属氧化物避雷器
Application Summary AI generated
This standard specifies technical requirements, test methods, and acceptance criteria for metal-oxide surge arresters without gaps used in ±800kV ultra-high voltage direct current (UHVDC) transmission systems. It is applied in the design, manufacturing, and quality verification of arresters that protect converter stations and DC transmission lines from overvoltages caused by lightning strikes or switching operations. The standard ensures reliable insulation coordination and operational safety in China's long-distance, high-capacity UHVDC power transmission projects.
