The KYN28-12 is a mainstream indoor armored withdrawable AC metal-enclosed medium voltage switchgear designed for 12kV (10kV) 50/60Hz three-phase AC power grids. As a standard core power distribution device, it is extensively used in urban substations, industrial factories, commercial buildings, railway stations, data centers and new energy power stations for power receiving, distribution, circuit protection, fault isolation and real-time electrical system monitoring.
Adopting integrated CNC manufacturing technology and modular assembled structure, the KYN28-12 switch cabinet features compact overall size, high structural rigidity and excellent corrosion resistance. Equipped with advanced vacuum interrupter and air insulation technology, the equipment achieves reliable arc extinction and stable closing/breaking performance, adapting to long-term continuous operation and frequent switching requirements in various indoor power scenarios.
Core Advantages
1. Strict Safety Protection: Equipped with a complete mechanical interlock system that meets five anti-misoperation rules, effectively avoiding manual misoperation risks. The IP4X protection grade provides reliable dustproof and anti-external interference capabilities, ensuring safe operation of equipment and staff.
2. Compact & Space-saving: Optimized internal layout and miniaturized structural design greatly reduce floor space, perfectly suitable for indoor power rooms with limited installation area and urban compact power distribution projects.
3. Low Maintenance & High Stability: Adopts withdrawable circuit breaker handcart structure, supporting quick replacement and overhaul without full power outage. The vacuum arc extinction structure has no combustion hazard, with low failure rate and long service life for continuous industrial operation.
4. Strong Compatibility & Customization: Supports multiple current specifications and functional module configurations. Reserved intelligent monitoring and communication interfaces, compatible with smart grid systems, meeting the upgrading and construction demands of modern intelligent power distribution projects.
