The KYN28A-12/24(Z) indoor AC metal-clad switchgear, often referred to simply as 'the cabinet,' is engineered to function seamlessly within a voltage range of 3.6 to 24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems. This state-of-the-art power distribution solution is indispensable in a myriad of settings, such as power plants, substations, industrial and mining enterprises, high-rise structures, and beyond. It excels in the reception and distribution of power while providing robust circuit control, unparalleled protection, and continuous monitoring.
Our product's circuit breaker is designed with a middle mounting mode, ensuring optimal stability and performance. Users can select between the VS1 (ZN63A) type or the VD4 type vacuum circuit breakers, offering significant flexibility. Furthermore, the cabinet is compatible with an extensive array of vacuum circuit breakers from both domestic and international manufacturers, accommodating a wide range of specifications and models to meet diverse needs.
Adhering to the stringent standards of 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,' our product ensures superior quality and reliability. These certifications underscore our commitment to excellence and adherence to the highest industry benchmarks.
