GB/T 22580-2008
ActiveSpecific environmental condition - Technical requirements of electric equipments used for plateau - Low-voltage switchgear and controlgear assemblies
特殊环境条件 高原电气设备技术要求 低压成套开关设备和控制设备
Application Summary AI generated
This standard specifies technical requirements for low-voltage switchgear and controlgear assemblies operating at altitudes above 2000 meters, where reduced air density affects insulation and heat dissipation. It is applied in the design, manufacturing, and testing of electrical distribution equipment for plateau regions such as the Qinghai-Tibet Plateau, ensuring safe and reliable performance under rarefied atmosphere and extreme temperature variations.
