KYN28A-12/24(Z) indoor AC metal-clad switchgear, known as the cabinet, operates within a 3.6-24KV range and supports a three-phase AC 50HZ single busbar, single busbar segmentation system. This comprehensive power distribution equipment is pivotal in power plants, substations, industrial enterprises, mining enterprises, and high-rise buildings, ensuring efficient power reception, distribution, circuit control, protection, and monitoring.
The circuit breaker embedded within the product is mounted in the middle. It offers flexibility with options like the VS1 (ZN63A) type or VD4 type vacuum circuit breakers, along with a variety of other domestic and international vacuum circuit breaker specifications and models.
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 1KV above 5CKV and below AC metal-enclosed switchgear and control equipment".
