HXGN□-12 · XGN-12 · ZSV-12 · GTXGN-12
Ring main units, 12 kV
12 kV · 630 A · 20–25 kA
The ring main range covers four insulation technologies. HXGN□-12 is the SF6 load-break unit; the XGN-12 family adds a vacuum (V) or SF6 (C) main switch, two environmentally friendly non-SF6 variants (ZSV-12 and XGN-12(V) eco), a two-way-plus-PT unit, and the GTXGN-12C solid-insulated unit.
Tested and certified
CN type test (HXGN); XIHARI reports for the XGN, ZSV and GTXGN variants
Built for
Urban distribution loops, Data centre MV rings, Industrial parks.
Standards
IEC 62271-200, GB 3906.

Production process
From enquiry to commissioning
- Enquiry and analysisSend a single-line diagram, load list or panel schedule. An engineer confirms voltage, short-circuit level, forms of separation and applicable standards within 24 hours.
- Proposal and drawingsBudgetary quotation in five working days, then general-arrangement drawings, busbar sizing and a bill of materials for approval.
- Order and engineeringApproved drawings release procurement of Schneider, ABB or specified components and sheet-metal programming.
- Fabrication and assemblyLaser cutting, CNC bending, powder coating, busbar processing, primary assembly and secondary wiring in Shaoshan.
- Factory acceptance testDielectric, loop-resistance, insulation, earth-continuity, IP and current-injection tests; customers and consultants welcome to witness.
- Delivery and after-salesExport packing, sea or air freight, commissioning support and a 7×24 service line with Schneider-trained engineers.
