The HXGN15-12 SF6 ring main unit (hereinafter referred to as the RMU) is a new generation of high-voltage switchgear developed by our company based on advanced foreign technology and in accordance with the requirements of urban power grid upgrades. After rigorous type testing and long-term operation assessments, all technical performance indicators fully comply with national standards.
The RMU adopts the FLN36-24 type SF6 switchgear as its main switch, operating mechanism, and core components. It is available in both manual and electric operation modes.
The cabinet is made of aluminum-zinc coated steel sheets, precisely processed by CNC machines and assembled with rivets. It features reliable mechanical interlocking and anti-misoperation functions.

Applications:
Widely used in industrial and mining enterprises, high-rise buildings, residential communities, and schools for 24kV ring network power distribution and terminal distribution.
Functional Capabilities:
The RMU is equipped with an SF6 load break switch, or a combination of SF6 load break switch and fuse unit. It can:
-
Make and break rated load current
-
Close rated short-circuit current
-
Interrupt transformer no-load current
-
When paired with fuses, interrupt short-circuit current up to 31.5kA in a single operation
This provides effective control and protection in medium-voltage power distribution systems.
