GIS | High-Voltage Gas Insulated Switchgear Substations Insulated Substations . A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible.
The world of high-voltage power | T&D World later were the phenomenal dielectric properties of sulfur hexafluoride (SF 6) gas discovered, which resulted in the introduction of the first high-voltage gas-insulated switchgear (GIS) by BBC, one of ABB's parent companies, in 1965 1. From then on the focus was on improving the understanding of breaker physics, which resulted in more ...
