Kyn28-12 Metal-Clad Switchgear High & Medium Voltage Withdrawable Vcb Panel

The KYN28-12 (GZS1) armored central AC metal-enclosed switchgear is designed for high-performance power distribution in three-phase AC 50Hz systems, with a rated voltage of 12kV. This switchgear is suitable for energy reception, distribution, control, and circuit protection, making it ideal for power stations, substations, and industrial facilities. It meets the requirements of GB3906, GB/T11022, and IEC60298 standards, ensuring reliable operation in demanding environments.

Features

• Robust and Versatile Design: The KYN28-12 is built with a metal armor structure and features modular components for flexible installation and maintenance. This design supports various operational configurations and facilitates seamless integration with high voltage power systems.
• Reliable Circuit Protection: Equipped with ZN63A-12 (VS1) or imported VD4 vacuum circuit breakers, the switchgear offers high short-circuit breaking capacity and stability, with options for manual or electric operation. The breakers are housed in an IP4X-rated enclosure to provide high protection against dust and contaminants.
• Enhanced Safety Measures: The switchgear includes a comprehensive interlocking system that meets the "five prevention" standards, preventing misoperation and enhancing operator safety. Additionally, pressure relief channels in the high-pressure compartment further ensure personnel safety.
• Convenient Operation and Monitoring: Each circuit breaker compartment is equipped with positioning and display devices, while an observation window on the front panel allows operators to monitor internal components without opening the cabinet.
