Sf6 gas Insulated RMU
Sf6 gas Insulated Switchgear
Minimization of volume, custom interface, convenient and reliable installation.
Pressure interface customised to customer requirements.
A plurality of switching contacts according to the needs of the user can be provided.
SF6 gas density monitor can be calibrated or replaced without disassembling an SF6 density monitor.
If the screws are not disassembled, a person can operate independently, which saves effort and time.
On-site staff can be able to measure micro-water and supplement air to a switch
Avoid surface sealing and joint damage caused by disassembly
