  KYN28A-12 Type Armored Withdrawable AC Metal-Enclosed Switchgear

  The KYN28A-12 armored withdrawable AC metal-enclosed switchgear is suitable for indoor three-phase 50 Hz power systems with a rated voltage of 12 kV . It is mainly used in power plants, substations, industrial and mining enterprises, and high-rise buildings for receiving and distributing electrical energy and controlling, protecting, and monitoring circuits. The KYN28A-12 switchgear has various functions to prevent misoperation, including preventing the moving of the switchgear under load, preventing the closing of the circuit breaker in the closed position of the grounding switch, preventing the closing of the grounding switch while it is energized, and preventing accidental entry into energized compartments. The KYN28A-12 switchgear is equipped with high-performance 3 AH2-12 and VBC- 12 high-voltage AC vacuum circuit breakers. The secondary circuit of the switchgear is equipped with advanced and reliable control and protection components. The busbars use heat-shrink tubing for insulation, and the electrode shape is optimized. The cabinet structure is compact. The KYN28A-12 switchgear is a technologically advanced, stable, structurally sound, easy-to-use, safe, and reliable power distribution device.

  XGN2-12 Box-type Fixed Metal Enclosed Switchgear

  The XGN2-12 box-type fixed metal-enclosed switchgear can be used in single busbar and single busbar with bypass systems, and features a fully enclosed structure. No insulating partitions of any kind are used inside the cabinet, and the air insulation distance is greater than 125 mm . The use of large creepage distance insulating bushings gives the switchgear high insulation and stability. The disc-type five-proof operating mechanism simplifies the interlocking device structure and ensures reliable operation.
