72/84 kV new compact gas insulated switchgears for utilities

摘要

Gas Insulated Switchgear (GIS) has made a great contribution to the modernization and size reduction of substations. Nissin has accumlated technique and experience through the great number of supply records. Based on this expertise, we have developed the new compact type 72/84 kV GJS to achieve higher reliability and size reduction. In this paper, we descrive the outline of this newly developed 72/84 kV GIS.
