Modular system to fulfil user requirements
Complete single or three-phase enclosed construction and compact design ensuring reduced space requirement
Aluminium enclosures result in low enclosure losses, are light weight and corrosion free
Low maintenance requirement, high availability and long service life
Engineered Gas Schematic for achieving Service Continuity as per Customer Requirement and or as per IEC Standard
The thermo-dilatation and installation tolerances are compensated by expansion joints
Compact and optimal Bay footprintGas Insulated Substation (GIS) from 72.5kV to 245kV. CG has supplied its High Voltage GIS to various utilities spread across different climatic conditions such as sub-zero temperature in Ukraine and in Himachal Pradesh to hot and humid in Mumbai and Surat in India. Our GIS adhere to the requirements of the National and International Quality, Environment and Safety Standards including ISO 9001–2015, ISO 14001 and ISO 18001. The performance and reliability of GIS has been verified through Type tests at renowned international testing laboratories like KERI (South Korea) and ERDA (India), including Short Circuit Making and breaking, Switching Tests, Dielectric Tests including Power Frequency Withstand, Lightning Impulse and Partial Discharge test etc as per IEC 62271-100.
