Incoming material
Silicon steel, copper and aluminium conductors, insulating oil, epoxy resin, bushings and tap changers are checked against the purchase specification. Material certificates are retained for traceability. Critical suppliers are reviewed on delivery performance and test results.
Process control
Core cutting, stacking, winding, vacuum casting, tank welding, oil filling and final assembly each have a hold point. The approved drawing, not a generic catalogue, is the reference. Deviations are recorded and closed before the next stage.
Routine test
Each unit is tested for winding resistance, ratio, impedance, no-load loss, load loss, insulation resistance and power-frequency withstand. Oil-immersed units also receive an oil test. Partial-discharge and temperature-rise tests are included for dry-type projects where specified.
Documentation
The shipment document pack includes the approved GA drawing, nameplate data, routine test report, oil report where applicable, installation and maintenance manual, and packing list. Third-party inspection can be arranged.
Certificates
Quality system certificates, high-tech enterprise recognition, credit certificates and product test reports are available for project pre-qualification. The relevant documents are shared during the tender or supplier-audit process.
