GB/T 20635-2006
Scope
This standard specifies the special technical requirements related to the surrounding atmosphere when high-voltage electrical equipment works in high-altitude areas above 1000m above sea level and not exceeding 5000m above sea level. This standard applies to high-voltage electrical equipment used in three-phase AC power systems and DC power systems with a maximum voltage greater than 1kv. These equipment include: circuit breakers, isolating switches, load switches, earthing switches, fuses, lightning arresters, and current-limiting reactors. , current transformers, combined electrical appliances and complete power distribution devices, etc. Also suitable for single-phase and two-phase systems.
