XGN15-12 unit type SF6 ring network cabinet
I want to make an inquiry
XGN15-12 unit type sulphur hexafluoride ring network cabinet (hereinafter referred to as unit cabinet) is a new generation of high-voltage electrical products produced by introducing foreign advanced technology and in accordance with the requirements of domestic agricultural network and urban network transformation. The main switch, operating mechanism and components of the unit cabinet adopt ABB original SFL-12/24 type or domestic high quality product FLN36-12D type SF6 switch equipment. It can also be equipped with ABB original HAD/US type SF6 open circuit according to user needs. Or VD4-S vacuum circuit breaker. Its operation mode can be divided into manual and electric. After strict type test and long-term operation assessment, the technical performance indicators of the cabinet all meet the GB3906 and IEC298 standards, which are applicable to the 12KV power network as the acceptance and distribution of electric energy.
◆The cabinet body is riveted with 2mm thick aluminum-zinc plate. There are two pressure reliefs L behind the cabinet, one for the cable compartment and the other for the load switch/busbar compartment. The structure can ensure personal safety and reliable operation of the equipment to the maximum extent, the protection level is 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, and less maintenance.
