Indoor Gas - Insulated Medium Voltage Switchgear 10kV GIS Ring Main Unit Cabinet

Indoor 10kV MV GIS Ring Main Unit Switchgear , Gas - Insulated Safering Cabinet

General

XGN58(HXGT6A)-12/24 Switchgear(RMU) is a kind of composite apparatus which seals all themain circuits switches in a metal enclosure and uses SF6 gas as arc-extinguishing and insulation medium. It is suitable for RMU and double radiation power supply in 12/24kV power supply circuit. The product is especially suitable for industrial and commercial zones or rural area, which have high-density power supply load and use cable feed network. Meanwhile, the RMU has the advantages of safe operation, no weather influence, easy installation, lttemaintenance and space saving, which is suitable to be installed in box-type substation. TheRMU can be flexibly combined by the extension of bus bars.

Service Conditions

1. Altitude: Not more than 3000m above the sea level;

2. Ambient temperature: Max: +40C, Min: -40"C;
3. Relative humidity: Daily average is not more than95%, monthlyaverage is not more than 90%;
4. No apparent pollution of corrosive or combustible gas around,Seismic intensity is not more than eight class.
5. No regular violent vibration, Seismic intensity is not more thaneight class;

Note: if deviation of normal service conditions occurs, the customer can negotiate with the manufacturer.

Technical characteristics
► Equipped with load switch, load swithfuse composite apparatus, circuit breaker function unit, its function is very complete.
►Small volume, light weight, minimum volume for one single is 350*820* 1500(mm).
►Easy operation, safe use, convenient maintenance, the
switchgear can be used for 30 years without maintenance.
►RMU is designed to be omniseal, without exposed live part and can run for a long term in the adverse environment.
