Description
High Voltage Fixed SF6 Ring Main Unit
XGN series SF6 ring main unit type AC metal-enclosed switchgear is a new generation of high-voltage electrical products that we have designed and developed successfully after introducing advanced foreign technology and in accordance with the requirements of domestic electricity and urban network transformation. All technical performance indicators are fully IEC62271-200: 2003 and GB3906 standards.
The main switch, operating mechanism and components of the SF6 ring main unit adopt ABB original parts or imported parts SFL-12/24 type switchgear produced domestically, and can also be equipped with ABB company original HAD/US type SF6 according to user needs. . Circuit breaker or VD4-S vacuum circuit breaker. The operation mode is divided into two types: dynamic and electric.
The switchgear cabinet is formed by riveting after CNC machine tool processing, the protection level reaches IP3X, and it has reliable mechanical interlocking and anti-misoperation functions. This product has remarkable characteristics such as small size, light weight, beautiful appearance, easy operation, long life, high parameters, no pollution, and low maintenance.
