Primary Gas Insulated Switchgear

Primary Gas-Insulated Switchgear offers high performance in a compact design, with advanced features like arc flash protection and condition monitoring to extend switchboard lifespan.

What is primary Gas-Insulated switchgear (GIS)?​

Medium voltage switchgear for primary distribution up to 52 kV using gas as insulation, enclosed in a metal enclosure and including high-voltage components like circuit breakers and disconnectors.​

What are the benefits of primary GIS?​

• Space efficiency: Compact for use where space is limited, with applications from transformer substations to primary power supplies.​
• Reliability and longevity: The sealed design withstands harsh environments and offers long life with minimal maintenance.​
• Enhanced safety: Internal arc resistance and robust construction, including safety devices to protect operators and equipment from overloads and short circuits.​

What are key features of primary GIS?​

Compact size, high reliability, and strong performance.​

Where is it used?​

GIS is used in mining, petrochemical, oil and gas, renewables, container substations, railways, wind power, and critical infrastructure.​
