III Structure description
1. The frame of HXGN-10 ring main unit is assembled with foreign advanced technology profiles, and the overall structure is firm. The top of the cabinet is the bus room, the front of the bus room is the instrument room, and the middle and upper parts of the cabinet are the installation positions of the load beginning. The lower part is installed with current incoming and outgoing lines and other components (such as CT, PT). Each room is reliably separated.
2. The main switch adopts Italian advanced technology, and the imported ISARC load switch or FN12A-10D/630 pneumatic load switch with static contact insulation cover has stable and reliable performance. (The main switch can also use the vacuum load switch or sulfur hexafluoride switch according to user requirements)
3. The cabinet body has a perfect device to prevent electrical misoperation.
4. The cabinet body is small, occupies less land, and is safe and reliable.
