Medium-voltage switchgear systems (eg Ormazabal, Siemens)

The system's modular design provides clear benefits for both electricity grids operated by utilities and for industrial applications. The removable switchboard units ensure a high degree of availability, easy maintenance and fault remedying. The internal arc-resistance construction ensures optimum safety and the locked switching devices guarantee fault-free and reliable operation.

Areas of application

Air-insulated, metal-encapsulated type EA switchgear systems are ideally suited for installation in:

• Switchgear rooms
• Walk-in substations

Chief applications

• Distribution substations run by power supply companies, and
• Incoming substations in the power supply grid (with or without metering/billing)
• Industrial substations for measuring the consumption of individual plants (with or without metering/billing)
