HXGN15-12/24/40.5KV High Voltage Fixed SF6 Ring Main Unit(RMU)

HXGN15 series is composed by standard finished function units from our company, it adopts advantaged FLN36 load break switch (LBS), use SF6 gas with superior performance as arcing insulating medium.It is small ,compact and convenient installation, safety, stable working.

It is widely used in 7.2~40.5kV electric power distribution system.

The switchgear meet the requirements of standard IEC62271-200,IEC62271-100 etc.

Product Highlights
  • Pressure release :There have two pressure release exits for bus room & cable room to ensure the pressure release under the condition of extreme to ensure person safety.
  • Three position/double position:Natural interlock switch, only in “Close “,”Earthing “ or “Interlock” 3 position
  • Interlock position:Switch is interlocked with operation structure to avoid misoperation High voltage cable room is interlocked with operation structure to avoid opening the installation door under the condition of switch non-grounding to protect person safety.
  • Panel Display:Panel analog primary circuit and clearly display that charge display can flash to display the electric parts. Five independently intervals to avoid the accident spread.
