Immediate ConsultationProduct Introduction
The KYN28-12(Z) type indoor AC metal-clad removable switchgear is a complete distribution device with a rated voltage of 3 to 12KV, three-phase AC 50HZ, single busbar, and single busbar sectional system. It is used for power delivery in power plants, electrical systems, and substations of industrial and mining enterprises for power receiving, distribution, and high-voltage motor starting, achieving control, protection, and detection purposes. This switchgear meets the requirements of standards such as GB3906 and IEC298, and has five prevention functions: preventing misoperation of the circuit breaker, preventing the trolley from being pushed or pulled under load, preventing the grounding switch from closing under load, preventing power delivery when the grounding switch is in the grounding position, and preventing accidental entry into live compartments. The switchgear can be equipped with ABB's VD4 vacuum circuit breaker or domestically produced VS1 vacuum circuit breaker, making it a superior performance distribution device.
Product Features
1. The cabinet structure is made of aluminum-zinc plate processed by CNC machine tools and connected after multiple bending processes.
2. All operations are performed with the cabinet door closed.
3. High protection level, can prevent debris and pests from entering.
4. Simple and effective "five prevention" locking mechanism to prevent misoperation.
5. Can be equipped with VS1 and VD4 type vacuum circuit breakers.
6. Simple circuit breaker replacement, good interchangeability of trolleys.
7. The cabinet can be reliably wall-mounted, with front maintenance, reducing the footprint.
8. Ample space in the cable room, can connect multiple cables.
9. The circuit breaker room and cable room can be equipped with heaters to prevent condensation and corrosion.
