Modular SF6 RMU for 12/24/40.5 kV: C/F/V/SV/SL/M/PT units freely combined in a sealed IP67 gas tank, with left/right extension and flexible cable entry.
The HP-SRM series is a fully sealed SF6 gas-insulated ring main unit for 12/24/40.5 kV distribution. Functional units — load-switch (C), fuse-combination (F), vacuum-breaker (V), bus-sectioning (SV/SL), metering (M) and PT cabinets — can be combined in a common tank, with optional left/right extension and left/right/both-side cable entry to suit any network layout.
Rated voltage: 12 / 24 / 40.5 kV
Cabinet type: C load switch · F fuse combination · V vacuum breaker · SV/SL bus sectioning · M metering · PT cabinet (tank-type units combine C/F/V/SV/SL freely)
Rated current: 630 A or 1250 A
Extension: I left · D right · ID both sides · blank non-extendable
Cable entry: L left · R right · LR both sides
Example: HP-SRM-12-V-12/630DL — load-switch cabinet, 12 kV, 630 A, right extension, left cable entry
Normal indoor service; ambient max +40 °C (24 h average +35 °C)
Relative humidity ≤ 95 % (24 h) / ≤ 90 % (monthly)
SF6 rated pressure 14 bar at 20 °C; annual leakage ≤ 0.05 %
