Features
- Modular design, where each unit module can be combined and expanded arbitrarily, facilitating flexible system configurations and wide adaptability.
- The cabinet adopts an armored structure with metal partitions between compartments.
- The operating mechanism adopts corrosion-resistant metals, and the rotating parts are designed with self-lubricating bearings, ensuring unaffected performance in various environments and eliminating the need for regular maintenance.
- To accommodate power grid automation and improve distribution reliability, it can be equipped with motorized mechanisms, distribution network control terminal units, and possess telecontrol functions.
- The compact design of the cabinet incorporates a three-position rotary load switch, effectively reducing the number of components and enabling mechanical interlocking for five protection measures.
- The primary circuit simulation single-line diagram and analog display can demonstrate the internal status of the switch, enabling easy, accurate, and safe operation.

Structure
- Busbar room: The busbar room is arranged at the upper part of the cabinet. In the busbar room, the main busbar is connected and runs through the entire row of switchgear.
- Load switch: There is a three-position load switch installed in the switch room. The shell of the load switch is made of epoxy resin cast columns, and filled with sulfur hexafluoride (SF6) gas as the insulation medium. SF6 gas density meters or gas density meters with alarm contacts can be installed in the switch room according to customer requirements.
- Cable room: The load switch has a spacious cable room, mainly used for cable connections. With sufficient space also to install lightning arresters, current transformers, lower grounding switches, and other components.
- Operating mechanism, interlock mechanism, and low-voltage control room: The low-voltage room with interlocking functions as a control panel. Spring operating mechanism and mechanical interlocking device with a position indicator installed in a low-voltage room. The low-voltage room can also be equipped with auxiliary contacts, trip coils, emergency trip mechanisms, capacitive live displays, keylocks, and electric operating devices. The low-voltage room space can also be used to install control circuits, metering instruments, and protective relays. The 750mm wide cabinet has two identical low-voltage chambers, which can hold more accessories.
The whole XGN15 switchgear can be divided into upper and lower parts. The upper part of the cabinet includes a busbar room, a load switch, an operating mechanism, and a low-voltage room, which is separated from the lower part of the cabinet. Therefore, it is safer and easier to repair and modify the equipment installed in the upper unit, and to replace the whole upper unit.
