GGD
Main LV switchboard, fixed
380 V · ≤ 3150 A · 30 / 50 / 70 kA
GGD is the fixed low-voltage switchgear designed with the Department of Energy and design institutes for power plants, substations and factories at 380 V up to 3150 A. It is the drop-in successor to older fixed switchboards, with high breaking capacity and dynamic-thermal stability.
Tested and certified
CCC type test 400–4000 A; CN type test
Built for
Power plants, Substations, Factories.
Standards
IEC 439, GB 7251.

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.
