Indoor High Voltage Disconnector
The SGGN6-12 series Indoor High Voltage Disconnector is designed for power systems with rated voltages of 6-12kV and rated frequencies of 50-60Hz. Equipped with a CS6-1 manual operating mechanism, it serves to isolate circuits and provide protective earthing during maintenance when the system is energized but under no-load conditions. This ensures reliable isolation from the main circuit and grounding during circuit breaker or other component maintenance, thereby guaranteeing personnel safety.
