We also have the capability to manufacture gas insulated switchgear (“GIS”), which is used in high voltage power networks to safely and reliably control and protect electrical equipment in compact environments such as electrical substations. We have a technical collaboration with Chung HSIN Electric and Machinery Manufacturing Corporation, Taiwan (“CHEM Taiwan”), who is global player in GIS SF6 technology (Source: CARE Report dated January 23, 2026). Under the collaboration agreement with CHEM Taiwan, we have manufactured and supplied up to 252 kV GIS bays from our Gangol Plant to transmission utilities of Uttarakhand and Himachal Pradesh.
