‹ Prefabricated Substation
YB□-12/0.4
Prefabricated compact substation
12 / 0.4 kV · 800–1250 kVA · 0.69 kV / 3150 kVA
The YB prefab substation combines MV switchgear, distribution transformer, LV switchgear, metering and reactive compensation to a scheme, in a strong, ventilated double-layer composite shell. It suits grid renewal, residential estates, industrial sites, airports, rail, docks, temporary supply and renewable collector duty.

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.
