HLC-12 Modular Gas-Insulated Ring Main Unit (12kV)

HLXGN-12 Gas-Insulated Ring Main Unit (12 kV)
A unit-type gas-insulated metal-enclosed switchgear for 12 kV, three-phase 50 Hz distribution and ring main systems, designed for urban power grids, prefabricated/compact substations, and renewable energy integration. The sealed gas compartment (IP67, annual leakage rate ≤ 0.01%) houses the load switch, making the entire unit maintenance-free, compact, and fully interlocked, with a mechanical lifespan of up to 10,000 operations.
