Aparamenta metálica aislada por gas (GIS)

Visión general

The Metal-Enclosed Gas-Insulated Switchgear, abbreviated as GI, uses low-pressure SF6 gas as the insulating medium.with vacuum circuit breakers and three-position switches as the main primary components, sealed inside a pressurized compartment. It is primarily used in power plants for auxiliary power, substations in transmission and distribution systemsdistribution systems in industrial and commercial enterprises, as well as in environments with high humidity (or condensation)high altitudes, and polluted conditions, for control, protection, and monitoring. Compared to conventional airinsulated switchgear, GIS offers significant advantages in terms of cost-effectiveness, applicability, and reliability.

Destacados

Compact structure, small size, and low footprint.
Maintenance-Free: The primary components are fully sealed within a stainless steel-welded sealed gas chamber, filled with SF6 gas as the insulating medium. With an IP67 protection rating,it effectively prevents external environmental impacts on the switchgear, ensuring reliable operation in harsh environments such as basements, plateaus, permatrost areas, coastal regions,and humid conditions, achieving a maintenance-tree design.
Safety and ReliabilityThe switchgear is equipped with reliable five-lock mechanicalinterlocks, which prevent incorrect operations. All high-voltagecomponents, including cable terminals, surge arresters, and the metal enclosure, are sealed, ensuring safe and touchablesurtaces.
Simple Installation and Operation The modular design offers flexible configurations, making operation, installation, and replacement easy and convenient.
