Structure
The switch cabinet is a metal enclosed box structure. The skeleton of the cabinet is welded by angle steel, and the cabinet is divided into circuit breaker room, busbar room, cable room, instrument room, and the rooms are separated by metal steel plates.
Main feature:
1. The cabinet structure is assembled, stable and reliable, and easy to combine. It can form a ring network power supply unit and various wiring methods.
2. Small size, light weight, small footprint, easy to install.
3. The ring main unit has three safe and independent partitions: busbar room, switch room and instrument compartment. The specific cabinet and each component have reliable safety grounding to ensure the personal safety of operators and maintenance workers.
4. The ring main unit can be equipped with load switches such as FN12-12D and FN25-12D.
5. The mechanical interlock is advanced and reliable, and fully meets the requirements of "five protections".
