Ensure Every Order Is Produced On Time, with Quality Assured.
Step 1: Confirm Requirements
We review the key basics first, including rating, voltage, standards, and delivery expectations.
Step 2: Proposal & Drawings
Technical details are aligned early through proposal sheets, drawings, or specification confirmation.
Step 3: Material Inspection
Key materials are checked before production starts to reduce errors and keep quality under control.
Step 4: Core Processing
Core cutting, stacking, or related processing is carried out under controlled production standards.
Step 5: Coil Winding
Coils are produced according to the confirmed design, with process control for consistency and traceability.
Step 6: Insulation Treatment
Required drying, curing, or insulation processes are applied based on the product type and design needs.
Step 7: Final Assembly
Main components are assembled and key connections are checked to support reliable operation.
Step 8: Routine Testing

Transformer FAQs
In today’s tight transformer market, what is your typical lead time?
Lead time depends on rating, voltage class, IEC/ANSI requirements, and customization level. Typically, standard distribution and mid-size units are 12–20 weeks. If stock units are available, we can deliver in 2–6 weeks through a rapid retrofit program. Once we receive your key parameters, we’ll issue a practical delivery milestone plan (design → production → FAT → shipment).
How do you manage copper/steel price fluctuations to keep quotations and project budgets under control?
We offer two mechanisms: a short quotation validity (market-linked) and project price/material locking for budget control on major orders. At contract stage, we clarify the cost structure and critical material strategy to reduce budget risk from commodity volatility.
Can you manufacture transformers compliant with IEC and ANSI/IEEE standards? How do you reduce acceptance risk?
Yes. We support both IEC 60076 and ANSI/IEEE C57 systems. To reduce acceptance risk, we confirm temperature rise, insulation/BIL, losses/efficiency, short-circuit withstand, noise, and test scope in the technical agreement, and provide a compliance matrix before FAT.
What FAT (Factory Acceptance Tests) do you perform before shipment? Can overseas customers witness the tests remotely?
We perform FAT per IEC/IEEE standards, typically including ratio, winding resistance, insulation tests, applied/induced voltage tests, no-load/load losses, and impedance. Temperature rise, impulse, partial discharge, and noise tests are available upon request. We also offer remote FAT witnessing via live video, allowing you to view the procedure and readings in real time and align key points with our engineers.
If I can’t visit the factory in China, how can I verify you are a real manufacturer and ensure reliable quality?
We provide a verifiable “trust pack”: factory videos and key equipment list, production/testing process overview, reference projects (redacted if needed), management system certificates, and optional third-party audits (e.g., SGS/TÜV) upon request. We also support remote video factory audits and remote FAT witnessing to ensure transparent, traceable quality.
Transformers are heavy and oversized—how do you prevent damage during transportation?
We apply export-grade packing and lashing plans and can install shock/tilt indicators to track abnormal impacts during transit. Oil-immersed and dry-type units use different moisture-proof and reinforcement methods (e.g., nitrogen/filled-oil options, vacuum moisture-proof packing—project-dependent). We also provide packing and lashing photo records for receiving inspection.
