Ring Main Units (RMU) / Modular C-GIS RMU
HLC-12 Gas-Insulated Modular RMU / C-GIS (12 kV)
A gas-insulated, fully sealed modular ring-main unit (C-GIS style) for 12 kV ring-network and cable distribution. Built from independent functional units — C (load-switch / cable), F (load-switch-fuse) and V (vacuum circuit breaker) — so configurations can be combined per project. A pressurized gas tank (IP67, ≤ 0.01 % annual leakage) and IK10-rated, IP54 switchgear body deliver a compact, maintenance-free unit for urban and underground networks.
