KYN28A-12 Series
KYN28A-12 Metal-Clad Withdrawable Switchgear
Why choose ZY POWER for this project
Metal-clad withdrawable construction
KYN28A-12 uses a compartmentalized indoor structure with withdrawable breaker truck, helping maintenance teams isolate, inspect and replace the breaker unit more efficiently.
Flexible feeder configuration
Incoming, outgoing, bus tie, metering, transformer feeder, motor feeder and capacitor feeder panels can be arranged according to the single-line diagram.
Protection and metering integration
Protection relays, CTs, VTs, meters, auxiliary contacts and communication interfaces can be configured for utility, industrial and EPC project requirements.
Factory-tested panel assembly
Mechanical operation, interlocking, wiring continuity, insulation and power-frequency withstand checks can be completed before packing and shipment.
