GB/T 22383-2017
ActiveRigid gas-insulated transmission lines for rated voltage of 72.5kV and above
额定电压72.5 kV 及以上刚性气体绝缘输电线路
Application Summary AI generated
This standard specifies technical requirements, test methods, and acceptance criteria for rigid gas-insulated transmission lines (GIL) designed for rated voltages of 72.5 kV and above. It is applied in the design, manufacturing, and quality inspection of high-voltage underground or enclosed power transmission systems, typically used in substations, tunnels, or urban power grids where overhead lines are impractical. The standard ensures safe and reliable operation under high electrical stress, with sulfur hexafluoride (SF6) or similar gas mixtures serving as the insulating medium.
