KYN28A-12 High-voltage Medium-mounted Withdrawable Switchgear

The KYN28-12kV is an indoor AC metal-clad withdrawable switchgear designed for three-phase power systems with a rated voltage of 12kV and frequency of 50/60Hz. It serves as a critical component for receiving, distributing, and managing electrical power in the following applications:

• Power plants
• Substations
• Industrial and mining facilities
• High-rise buildings

Core Functions:

1. Power Control: Enables efficient switching and load management.
2. Protection: Safeguards circuits against overloads, short circuits, and faults.
3. Monitoring: Supports real-time electrical parameter detection (e.g., current, voltage).
