GB/T 20645-2006
AbolishedSpecific environmental condition - Technical requirements of low-voltage apparatuses for plateau
特殊环境条件 高原用低压电器技术要求
Application Summary AI generated
This standard specifies technical requirements for low-voltage electrical apparatuses operating at altitudes above 2,000 meters, where reduced air density affects insulation, heat dissipation, and arc extinction. It is applied in plateau regions, such as the Qinghai-Tibet Plateau, for designing, testing, and selecting devices like circuit breakers and contactors used in power distribution and industrial control systems. The standard ensures safe and reliable performance under low-pressure, high-ultraviolet, and wide-temperature-range conditions.
