KYN28-12 HV Switchgear | 10kV Metal-Clad Withdrawable Switchboard

The KYN28-12 indoor metal-clad withdrawable switchgear (hereinafter referred to as switchgear) is currently the most advanced domestic product with modern and international standards. It is a complete set of distribution equipment for 3–10kV three-phase AC 50Hz single-busbar segmented systems. It is primarily used for power transmission from power plants and small-to-medium generators, power distribution in industrial and mining enterprises, and receiving/sending power and starting large HV motors in secondary substations of utility systems, providing control, protection, and monitoring functions. It features interlock functions to prevent: pushing/pulling the circuit breaker truck under load, incorrect opening/closing of the circuit breaker, closing the circuit breaker when the earthing switch is closed, entering live compartments by mistake, and closing the earthing switch while energized. It can be equipped with either VS1 or ABB’s VD4 vacuum circuit breakers, making it a high-performance distribution solution.
