The KYN28A-12/24(Z) indoor AC metal-clad switchgear, often referred to as the cabinet, operates efficiently within a voltage range of 3.6 to 24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems. This versatile and robust power distribution equipment is widely used in power plants, substations, industrial and mining enterprises, high-rise buildings, and various other settings. It excels in the reception and distribution of power while providing superior circuit control, protection, and monitoring.
Our cutting-edge product features a circuit breaker that employs a middle mounting mode, offering users the flexibility to choose between the VS1 (ZN63A) type or VD4 type vacuum circuit breakers. Furthermore, it is compatible with an extensive range of vacuum circuit breakers from both domestic and international brands, catering to diverse specifications and models.
Standards Compliance: Our products strictly adhere to the following 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."
