The KYN28A-12/24(Z) indoor AC metal-clad switchgear, known colloquially as 'the cabinet,' is engineered for operational voltages spanning 3.6-24KV within three-phase AC 50HZ single busbar and single busbar segmentation systems. This versatile power distribution apparatus is widely utilized in power plants, substations, industrial and mining enterprises, high-rise edifices, and various other environments to facilitate power reception and distribution, as well as circuit control, protection, and monitoring.
Our sophisticated switchgear features a circuit breaker that embraces a middle mounting setup, allowing for the selection between the VS1 (ZN63A) type or VD4 type vacuum circuit breakers. Furthermore, it supports an extensive range of vacuum circuit breakers from a variety of domestic and international brands, ensuring compatibility with varied specifications and models.
Adherence to Standards: Our product strictly follows the 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."
