1 Scope
This Guidance Document specifies the conditions of use, ratings, design and construction of 1100kV gas-insulated metal-enclosed switchgear,
Test, selection guidelines, transportation, storage, installation, operation and maintenance requirements.
This guidance applies to 1100kV outdoor installation, frequency of 50Hz unipolar closed SF6 gas insulated metal closed
Off equipment.
In order to facilitate the use of this guidance document, the terms "GIS" and "switchgear" are used to describe "gas insulated metal enclosed switch
equipment".
The gas-insulated metal enclosed switchgear covered by this technical document consists of individual components that can be directly connected
And these components can only be operated this way.
As required, this Guidance Document complements and supplements the relevant standards for the individual components that make up GIS.
