PRODUCT CHARACTERISTICS
- The GCS type withdrawable low-voltage switchgear features high breaking capacity, excellent dynamic and thermal stability, flexible electrical configurations, strong serialization and applicability, innovative design, and high protection rating.
- The horizontally arranged busbars ensure superior dynamic and thermal stability of the device.
- Vertical busbars are sealed within high-strength flame-retardant and high-insulation plastic functional plates, providing arc fault resistance and ensuring safe and reliable operation and maintenance.
- The drawer’s operating mechanism and advancing interlock mechanism are integrated into one unit. The mechanism features clear indications for operational status, main switch disconnection, test, isolation, and withdrawn positions, ensuring secure and reliable operation.
- External cable connections are completed in the cable compartment, with cables entering/exiting from both top and bottom for convenient installation and maintenance.
- Clear and reliable separation between functional units and compartments ensures that faults are confined to the smallest possible area.
