GIS-type medium-voltage switchgear with full insulation in gas, up to 38 kV,  

in accordance with IEEE Standards

IG-197-US version 02; 07/11/2019

6.5  Equipment grounding

The cubicles grounding joint consists of three zones: top, 

bottom and top with bottom link.

6.5.1  Top section

The top area has copper bars when the busbar enclosure has 

protection for internal arc or voltage transformers in busbars.
