Product overview
HXGN15-12(SF6) type unit type AC metal closed ring network switchgear, is the introduction of foreign technology and in accordance with the domestic rural power and urban network transformation requirements of the design, the successful development of a new generation of high-voltage electrical products. The technical performance of the product all meet the IEC62271-200:2003 and GB3906 standard. The main switch, operating mechanism and components adopt ABB's original parts or SFL-12/24 switchgear assembled and produced domestically with imported parts. ABB's original HAD/US SF6 circuit breaker or VD4-S vacuum circuit breaker can also be equipped according to user's needs. The operation mode is divided into manual and electric. The cabinet body is riveted after being processed by CNC machine tools, the protection level reaches IP3X, and has reliable mechanical interlocking and anti-misoperation functions. This product has the characteristics of small size, light weight, beautiful appearance, easy operation, long life, high parameters, no pollution, less maintenance and so on. HXGN15-12(SF6) type unit type AC metal closed ring network switchgear is suitable for AC 50Hz, 12KV power network, as the receiving and distribution of electric energy.
