The KYN28A-12/24(Z) indoor AC metal-clad switchgear, also known as the cabinet, operates within a voltage range of 3.6-24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems. This versatile power distribution equipment is ideally suited for use in power plants, substations, industrial and mining enterprises, high-rise buildings, among other key environments. It is designed for the efficient reception and distribution of electricity, as well as for circuit control, protection, and monitoring.
Our circuit breaker is designed with a middle mounting mode, offering you the flexibility to choose between the VS1 (ZN63A) type or the VD4 type vacuum circuit breakers. It also supports a broad spectrum of vacuum circuit breakers from various leading domestic and international manufacturers, ensuring compatibility and reliability for diverse 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 above 1KV and below 5KV AC metal-enclosed switchgear and control equipment.'
