Gas-Insulated Switchgear (GIS)
When floor space is expensive or the environment is tough, this is your solution.
GIS encloses all critical components in a sealed, gas-filled steel tank. This approach offers three major benefits. First, it saves a tremendous amount of space—up to 70% compared to traditional designs—perfect for cities, ships, or plant expansions. Second, the sealed system is completely protected from dust, humidity, and salt air, guaranteeing performance in harsh locations. Third, it requires almost no routine maintenance. Once installed, it delivers reliable power with minimal operational cost, making it a smart long-term investment for critical applications.
As for the insulating gas: SF6 has been widely used for its strong insulation performance. But because it’s a potent greenhouse gas, the industry is shifting more and more to dry air or nitrogen mixtures—clean, safe, and eco-friendly alternatives that meet today’s green standards.
