MV Gas-Insulated Switchgear Ormazabal
Maximum Flexibility in Minimum Space
Safe and Reliable Power for your Electrical Network
Ormazabal’s CGM.3 and CGMCOSMOS GIS-type switchgear are modular, compact units designed for secondary medium voltage distribution networks (12–24–36 kV). Each module performs a specific function and features its own metal-enclosed housing, which contains a sealed stainless-steel tank filled with SF6 gas. Inside the tank are the switching and connection components.
These switchgear systems are ideal for a wide range of medium voltage installations, including:
Public distribution networks
Infrastructure and industrial facilities
Commercial buildings
Hospitals, hotels, and stadiums
Airports
Wind and solar farms


Key Features
Safety
Engineered to withstand the effects of internal arc faults.
All live components are enclosed within a sealed SF6 gas tank, ensuring complete insulation and safety.
Mechanical and electrical interlocks enable safe and reliable operation.
Efficiency & Flexibility
Modular design allows for custom configurations while occupying minimal space.
Modules can be electrically and mechanically connected without handling SF6 gas.
Switching devices and motorization units can be easily replaced without interrupting power supply.
Available Module Types
