Abstract

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 atmos­pheric 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.
