Core Advantages of Air Insulation Switchgear (KYN-28)
Full Isolated Compartment & High Safety Performance: The Air Insulation Switchgear (KYN-28) is divided into four independent metal compartments for busbar, circuit breaker, cable and instrument. Equipped with complete 5-prevention interlock system, it effectively prevents misoperation. Independent pressure relief channel ensures personnel safety under internal arc fault.
Convenient Maintenance & Excellent Serviceability: Adopt withdrawable vacuum circuit breaker truck. The breaker can be easily rolled out for inspection, testing or replacement without power cut for the whole substation. Components are fully visible, supporting fast troubleshooting and flexible on-site modification.
Cost-effective & Wide Application: Using air as insulating medium, no SF6 gas leakage risk. Mature and reliable structure with low purchase and spare parts cost. It complies with IEC standards, widely adopted for industrial plants, parks and commercial building indoor power distribution projects.
