IEC 62271-204:20 22作为IEC 62271-204:20 22 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62271-204:20 22适用于刚性高压气体？绝缘传输线（GIL），其中绝缘至少部分通过大气压下的空气以外的绝缘气体或气体混合物获得，用于额定电压高于52 kV的交流电，以及用于高达（包括）60 Hz的工作频率。第二版取消并取代了2011年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -更新以符合IEC 62271-1:20 17以及电压额定值和测试电压的一致性。 -增加了受压部件焊接和气密性的新信息。

IEC 62271-204:2022 is available as IEC 62271-204:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62271-204:2022 applies to rigid HV gas？insulated transmission lines (GIL) in which the insulation is obtained, at least partly, by an insulating gas or gas mixture other than air at atmos-pheric pressure, for alternating current of rated voltages above 52 kV, and for service frequencies up to and including 60 Hz. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- update to be in line with IEC 62271-1:2017 and alignment of the voltage ratings and the test voltages.
- addition of new information for welds on pressurized parts and gas tightness.
