Product Overview
The SF6 High Voltage Switchgear is designed for power plants, substations, combined substations, and electric power systems. This three-phase indoor AC single busbar and sectioning single busbar system operates at 50Hz with 35kV rated voltage, providing reliable control, acceptance, and distribution of electric power.
Key Design Features
- Reliable Operation: Each compartment is individually monitored and equipped with its own pressure relief device
- Enhanced Safety: Hermetically enclosed primary side components in gas-filled compartments provide protection against atmosphere, dirt, and dust
- Space Efficient: Compact footprint with all operations accessible from the switchgear front
- Cost Effective: Reduced space requirements, long service life, and maintenance-free gas compartments
