Quality built into every transformer
From specification review to final test reports, JINXING manages each order through defined checkpoints, traceable records and project-specific acceptance requirements.
Factory control you can review
Manufacturing, inspection and final verification are connected to the approved drawing and project test plan.
Six controlled stages from enquiry to shipment
A single quality route keeps engineering decisions, manufacturing checkpoints, testing and final documentation connected to the approved project specification.
Checks at the stages that matter
Inspection is integrated into production instead of being left until the transformer is complete.
Electrical verification before release
The final test plan is confirmed against the transformer type, applicable standard and contractual requirements. The following routine checks are commonly included where applicable.
Confirms voltage ratio, polarity and phase displacement.
Checks winding continuity and phase consistency.
Verifies insulation condition before dielectric testing.
Measures core performance at the specified condition.
Confirms losses and short-circuit impedance.
Validates dielectric withstand in accordance with the agreed standard.
Clear evidence for review, installation and handover
Document requirements are agreed at order stage so the final package matches the customer, consultant, EPC or utility review process.
Built to the standard agreed for the order
IEC 60076, IEEE C57, national standards and utility-specific requirements may apply depending on destination, voltage class and customer specification. Compliance, certification and test scope are confirmed per model and per order—never assumed from a general product claim.
Missing parameters and conflicting requirements are resolved before design approval.
Hold points, witness points and required records can be agreed in advance.
Approved revisions remain connected to drawings, nameplate data and test records.
Quality continues through packing and support
Before release, the transformer configuration, accessories, documentation, protection and shipping marks are checked against the order. Installation guidance, commissioning coordination and after-sales technical support remain connected to the approved documentation.
