Product Description
Introducing the KYN28A-12/24(Z) Indoor AC Metal-Clad Switchgear, often referred to as 'the cabinet.' This unit operates efficiently within a voltage range of 3.6-24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems. This highly versatile power distribution equipment is ideally suited for power plants, substations, industrial and mining enterprises, high-rise buildings, and a multitude of other applications. Its primary functions include power reception and distribution, along with circuit control, protection, and monitoring.
Our product's sophisticated circuit breaker features a middle mounting mode, offering flexibility with the choice between VS1 (ZN63A) type or VD4 type vacuum circuit breakers. Furthermore, it is compatible with a diverse array of vacuum circuit breakers from numerous domestic and international specifications and models, ensuring adaptability and convenience.
Standards compliance: 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.'
