1.3.2.2 GIS Enclosures
In some jurisdictions in the United States, local building codes require the use of the following standards for GIS enclosures:
ANSI/ASME B31.1: Power Piping
The ASME standards are not specifically intended for use for electrical enclosures, but are required in local building codes and are therefore relevant.
In Europe and in Canada, the standards developed by the European Committee for Electrotechnical Standardization (CENELEC) for GIS enclosures are commonly used:
CENELEC EN 50052 (2017): Specification for Cast Aluminum Alloy Enclosures for Gas‐Filled High‐Voltage Switchgear and Controlgear
CENELEC EN 50064‐1989 (2017): Specification for Wrought Aluminum and Aluminum‐Alloy Enclosures for Gas‐Filled High‐Voltage Switchgear and Controlgear
CENELEC EN 50069 (2019): Specification for Welded Composite Enclosures of Cast and Wrought Aluminum Alloys for Gas‐Filled High‐Voltage Switchgear and Controlgear
CENELEC EN 50089 (1994) revised version in 2022: Specification for Cast Resin Partitions for Metal‐Enclosed Gas‐Filled High‐Voltage Switchgear and Controlgear
In other regions, often other standards are in place for GIS enclosures.
