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.
