Ormazabal collaborates in innovative projects and provides solutions and products focused on improving the energy distribution efficiency in a continuous changing environment as driver and dynamic factor for smart grids.
Getting its DNA from decades of experience in research, design, develop, manufacture and installation of Medium Voltage (MV) switchgear, is now one of the world's biggest suppliers of medium voltage gas insulated switchgear (GIS). Today over 1.350.000 Ormazabal medium voltage functional units have been installed in the electrical networks of over 100 Utilities and 600 wind farms in more than 110 countries.
Padmounted Switchgear is a prefabricated switching and breaking outdoor substation. Installed at ground level, tested and supplied from the factory as a single unit. It is designed for Distribution Networks of rated voltage up to 27 or sub-transmission 38 kV. Reduced weight and dimensions enable simple handling and transportation.
Padmounted Switchgear P&C functionality can be easily adapted to comply with Customer needs thanks to low energy current and voltage sensors on cable connectors and protection instrument transformers installed on cable compartment. It can be also supplied fully assembled with a replaceable voltage transformer HV fuse protected for LV auxiliary supply for protection relay and remote control unit.
The Padmounted Switchgear complies with the requirements of IEEE standards:
- IEEE C57.12.28:2014 PadMounted Equipment-Enclosure Integrity
- IEEE C57.12.29:2014 PadMounted Equipment-Enclosure Integrity for Coastal Environments
Padmounted Switchgear incorporates worldwide proven GIS metal-enclosed switchgear:
- cgmcosmos or cgm.800 up to 27 kV / 600 or 800 A / 25 kA 1-3 s
- cgm.3 and cgm.800 up to 38 kV / 600 or 800 A / 25 kA 1-3 s
