The KYN28A-12/24(Z) indoor AC metal-clad switchgear, commonly known as the cabinet, is a versatile and robust power distribution solution. Operating within a range of 3.6-24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems, this comprehensive piece of equipment is indispensable in power plants, substations, industrial and mining enterprises, high-rise buildings, and various other settings. Its primary functions include the reception and distribution of power, as well as seamless circuit control, protection, and monitoring.
Our product's circuit breaker boasts a middle mounting mode, offering flexibility with choices between the VS1 (ZN63A) type or VD4 type vacuum circuit breakers. Additionally, it can accommodate a diverse array of vacuum circuit breakers from numerous domestic and international manufacturers, ensuring compatibility and performance.
Adhering to standards: GB3906-2006 "3.6kV~40.5kV AC metal-enclosed switchgear and control equipment", DL404-2007 "Indoor AC high-voltage switchgear ordering technical conditions", and IEC298 (1990) "Rated voltage above 1KV and below 5CKV AC metal-enclosed switchgear and control equipment".
