The KYN28A-12/24(Z) indoor AC metal-clad switchgear, often referred to simply as 'the cabinet,' operates within a robust range of 3.6-24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems. This state-of-the-art power distribution equipment is an essential asset in power plants, substations, industrial and mining enterprises, high-rise buildings, and a multitude of other environments. It is designed for the efficient reception and distribution of electrical power, alongside sophisticated circuit control, comprehensive protection, and real-time monitoring capabilities.
Our product's circuit breaker is engineered with a middle mounting mode, providing exceptional versatility with options for either VS1 (ZN63A) type or VD4 type vacuum circuit breakers. This high adaptability ensures compatibility with a diverse range of vacuum circuit breakers from numerous domestic and international manufacturers, offering a tailored solution that meets a broad spectrum of specifications and models.
Compliance with rigorous 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" ensures our product meets the highest benchmarks for quality and safety.
