Indoor 10kV MV GIS ring main unit switchgear, gas-insulated safety cabinet
XGN58-12/24 RMU is a kind of composite device that seals all main circuit switches in metal furniture, and uses SF6 gas as an extinguishing and insulating medium. It is suitable for RMU and dual radiation power supply in 12/24kV power supply circuit. This product is especially suitable for industrial and commercial areas or rural areas with high density power supply load and using cable supply network. RMU has the advantages of safe operation, no weather influence, easy installation and maintenance, and space saving, and is suitable for installation in box-type transmission stations.
Terms of Service
Note: If any deviation from normal service conditions occurs, the customer may negotiate with the manufacturer.
Equipped with a load switch, a load Swiss fuse combination device, and a circuit breaker, the RMU is fully functional.
It is compact and lightweight, with a minimum volume of 350*820*1500 mm for a single unit.
Simple operation, safe use, and convenient maintenance.
The switch device can be used for 30 years without maintenance.
The RMU is designed to operate in all areas without exposed components and can operate for long periods in adverse environments.
