DOCUMENTED MANAGEMENT SYSTEMS
Review Tianhua’s quality and environmental management certificate copies. Each document identifies Jiangsu Tianhua Transformer Co., Ltd., the manufacturing-related scope and the printed certificate term.
Management system certificates describe organizational scope; they do not certify every transformer model. The printed terms are subject to the certificates’ surveillance conditions. Request the latest copies and status confirmation for supplier approval.
DEFINE THE TECHNICAL BASIS
Confirm the product type, destination and purchaser specification before quotation. Applicable editions, acceptance limits and supporting evidence belong in the agreed technical schedule.
| Requirement | Reference for technical review | Confirm with your enquiry |
|---|---|---|
| Power & distribution transformers | IEC 60076-1 — General, with applicable parts of the series | Capacity, voltage ratio, frequency, vector group, impedance, losses and service conditions. |
| Dry-type transformers | IEC 60076-11 — Dry-type transformers, where applicable | Cooling, insulation, enclosure, temperature rise and any required environmental or fire behaviour classes. |
| Destination & utility requirements | Purchaser, utility and local requirements specified for the project | Required standard and edition, approval documents, test categories, inspection hold points and destination. |
IEC links describe the reference standards. Conformity and document availability must be confirmed for the selected Tianhua model and order.
FROM MATERIALS TO DISPATCH
Tianhua’s manufacturing documentation describes winding, vacuum drying, assembly and finished-product inspection. Build your project review around defined controls and an agreed inspection and test plan.
Confirm the duty, site conditions, drawings, applicable standards and acceptance criteria.
Review material identification and the relevant winding, drying and assembly controls.
Agree routine test records, witness points and any additional testing before production.
Confirm the documentation, nameplate, marking and packing requirements before dispatch.
These are enquiry and inspection-planning topics. The final test list, facilities, schedule and any additional costs depend on the selected design and agreed order.

BUYER QUESTIONS
No. A management system certificate covers the organization and its stated activities. Product conformity requires the applicable model specifications, test evidence and any project approvals.
Send the exact standard, edition and purchaser specification for technical review. We review the proposed design, deviations and test requirements against that schedule before order confirmation.
Request current management system certificates and status confirmation, the proposed model datasheet, drawings, a compliance schedule and the relevant test reports. Confirm report coverage against the offered rating and design.
Include witness inspection and third-party requirements in your enquiry. Hold points, notice periods, access arrangements and the inspection schedule need to be agreed before the order is released.
