The KYN28A-12/24(Z) indoor AC metal-clad switchgear, affectionately known as the cabinet, is engineered to operate within a versatile range of 3.6-24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems. This all-encompassing power distribution solution is a quintessential component in power plants, substations, industrial and mining enterprises, high-rise buildings, and a multitude of other environments for the reception and distribution of power, coupled with unparalleled circuit control, protection, and monitoring.
Our innovative product features a circuit breaker with a middle mounting mode, providing a versatile selection between VS1 (ZN63A) or VD4 type vacuum circuit breakers. Moreover, it supports an extensive variety of vacuum circuit breakers, accommodating an array of domestic and international specifications and models.
Adhering to industry-leading 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."
